VOLUMK NVIII. .4 iiioiiograpli of the species of CRYPTOHYPNUS of Boreal America. BY GEORGE H. HORN, M. D. In the printed and other comments which were made on Dr. Hamilton’s paper on the distribution of many species in common in the Arctic regions of both continents, my attention happened to be drawn especially to this genus from the fact that several forms had just appeared which seemed to be identical with those of Europe, and which had not, as yet, appeared in our lists. These were made the subject of a short note, in “ Entomological News,” which closer study has shown me to be inaccurate in many of its statements, due in part to the lack of types, and as much to important omissions of details in the best European descriptions. The subsequent pages will show that several of our forms are parallel with those of Europe, in fact deceptively resembling them, but are readily separated by excellent structural characters hitherto unobserved. The number of species of Cryptohypnus known being less than one hundred, has not made it unwieldy or difficult to handle, conse- quently but little attempt has been made to subdivide it. C. G. Thomson, in his Skand. Col. vi, restricts the name Cryptohypnus to those species which have the prosternal sutures straight and Negas- trius to those with the sutures arcuate, although he seems to place TRANS. AM. ENT. SOC. XVIII. (1) JANUARY, 1891. 2 GEO. H. HORN, M. D. greater reliance on other cliaracters which have far less value in a larger number of species. He again subdivides Negastrius, sepa- rating those s})ecies as Zorochrus which have the prosternal sutures double and excavate. If any division of Cryptohypnus be thought necessary, that based on the form of the prosternal sutures appears to be the only one desirable, from the fact that, between the two forms, the sharpest line of demarcation is observed. The existence of the double grooved sutures in a group of small species was first observed by Thomson, but cannot be used for generic separation as it would remove certain species from that close approxi- mation in which they should be placed. It has also been observed in our species of that series that the groove is far more distinctly defined in the female than in the male. It is in this group that very notable sexual peculiarities exist in the form of tubercles on the first or first two ventral segments in the males of Melsheimeri and caurimis respectively, or in a small ])ubescent spot at the middle of the second ventral in the female of c/radarms. In quadriguttatm (tetragraphii^) and dermestoides of Europe, the anterior tibiae are much broader in the male than in the female. These, too, have an elevation or tu- bercle on the first ventral segment of the male which seems to have escaped the notice of European students. Another sexual character has been observed in the two species with non-striate elytra. In the centre of the prosternum of the male is a small, densely punctured spot, bearing, in well-preserved speci- mens, a short brush of hair. One species, Httoralis, is notable in having much shorter legs than normal, the tibice beset with short, stiff, bristle-like hairs, after the manner of many arenicolous species. The tibial spurs are also better developed. In the species with the curved prosternal sutures the spurs are far less distinct than in those with straight sutures. It will be observed also that the terminal joint of the maxillary palpus varies in form, but without that degree of difference enabling the character to be used for systematic purposes. Illustrations will be found on the plate, to which the reader is referred. The species known to me seem to divide very naturally into groups, and it is proposed so to treat them to avoid the use of a long analytical table. They are, therefore, divided as follows ; Prosternal sutures straight, parallel, or very little convergent posteriorly 2. Prosternal sutures arcuate and very evidently convergent posteriorly 3. NORTH AMERICAN COLEOPTERA. 8 2. — Tibife stouter than usual, the outer side beset with short spinules, the spurs very distinct Group LITTORALIS. Tibiffi slender, not spinulose externally, the spurs usually very small and indistinct. Depressed opaque species, thorax coarsely and closely punctate. Group SQUALIDUS. More or less convex and shining, thorax variably punctate, but never opaque, the median line more or less impressed. Hind angles of thorax slender and divergent, the basal incisure well marked; surface not distinctly pubescent.. -Group HYPERBOREUS. Hind angles of thorax stouter, scarcely at all divergent, basal incisures feeble; surface pubescent Group ABBREVIATUS. 3. — Elytra with the striae entirely, or in great part obliterated ; in the latter case, those near the suture alone evident Group PECTORALIS. Elytra with all the striae entire 4. 4. — Depressed species, dorsum quite flat, surface opaque, densely punctulate and pubescent; hind angles of thorax with short carina. Group STRIATULUS. Convex species. Thorax coarsely granulate, usually with a smooth elevated median line. / Group CHORIS. Thorax unequally sculptured, either subasperate or more densely, coarsely punctate near apex, posteriorly smoother, median line usually smooth Group MELSHEIMERI. Thorax equally punctate, either sparsely or moderately closely ; elytra ornate Group PERPLEXUS. The groups which follow are arranged in a manner to show what seems to be a natural sequence based on facies. In conclusion, I wish to acknowledge my indebtedness to Dr. Hamilton and Mr. Ulke for the loan and gift of specimens, and to Mr. Blanchard for first having called my attention to the pubescent spot in the abdomen of gradarms, thereby suggesting a new line of investigation which has resulted profitably. Group LITTORALIS. Prosternal sutures straight, very nearly parallel. Maxillary palpi moderate in length, the last joint elongate oval, obliquely truncate at apex. Tibiae shorter than usual, the outer edge beset with short spinules, the terminal spurs well marked. Form robust, body ap- terous. This group contains but one species so unlike those which follow, as to lead to the supposition that it should be more completely sepa- rated. There are, however, no differences of sufficient importance to warrant generic separation. 4 GEO. H. HORN, M. D. littorali!4 Escb. — Form robust, convex, brownish piceous or darker fer- ruginous, scarcely sbining. sides of tborax (more broadly beneath) and elytra, antenme and legs yellowish testaceous; antennae rather stout, joints 6-10 as broad as long, eleventh oval ; bead sparsely, rather coarsely punctate ; thorax broader at middle than long, sides arcuate, sinuate in front of the hind angles, which are acute and feebly divergent, the carina short, hut well marked ; disc sparsely punctate, basal margin without trace of incisure: elytra oval, humeri obliquely rounded, disc rather deeply striate, strise, not punctate, intervals con- vex, sparsely punctate near the base, gradually becoming granulate toward the apex ; body beneath piceous, except the flanks of the prothorax, these finely punctate externally, more coarsely near the inargin ; under surface punctate, hut not closely, except on the last ventral segment, which is quite rugose. Length 8 — 11.5 mm. ; .32 — .46 ineh. In well preserved specimens the surface above and beneath is sparsely fulvo-pubescent. A variety entirely yellowish is mentioned by Mannerheim and Candeze, not the result of immaturity, as might be suspected, but truly varietal, as has been observed in many species living along the sea-coast. Seems to be abundant on the Alaskan sea-coast. Group HYPERBOREUS. Prosternal sutures straight, very slightly convergent posteriorly. Legs slender, tibial spurs small. Maxillary palpi not prominent, the last joint triangular, as in the squalidus group. Thorax smooth, sparsely punctate, median line more or less impressed, the basal in- cisures distinct, hind angles long, slender and divergent. Surface nearly, or quite glabrous, body winged. This group contains but three species, as far as known to me, espe- cially notable by their oblong, feebly convex form, nearly glabrous surface, subsulcate thorax with slender hind angles. The species are separated as follows : AntenuiB entirely ferruginous. Anteimse rather slender, the joints longer than wide g;raii(licollis. Antenna stouter, joints triangular, as wide as long liyperboretis. Antenna piceous, except at base, the joints longer than wide. Elytral intervals fiat Saiiboriii. Elytral intervals convex barbatiis. These inhabit the more northern or elevated regions of our country, one of them {hyperhorens) having a circum-polar distribution in both hemispheres. C’. graiKlicollis Lee. — Oblong, moderately convex, piceous shining, with faint metallic lustre, elytra paler than the thorax; surface scarcely pul)escent ; antcTina ferruginous, joints all longer than wide; front fiat, coarsely not closely NORTH AMERICAN COLEOPTERA. 5 punctate ; thorax distinctly longer than wide, sides scarcely arcuate, hind angles very slightly divergent, distinctly carinate, carina short, disc moderately convex, median line vaguely impressed posteriorly; surface sparsely punctate, a little more closely in front and near the front angles; elytra a little wider than the prothorax at their middle, humeri obtusely rounded ; disc moderately convex, rather deeply striate, strim punctate, intervals slightly convex, sparsely punc- tate ; prosternum moderately coarsely, but sparsely punctate, the lobe moderately prominent, arcuate in front, limited behind by a feeble transverse line, propleura; moderately closely coarsely punctate, with finer punctures between, not opaque; metasternum moderately closely punctate, punctuation coarse and fine inter- mixed ; abdomen similarly punctate, the last segment more coarsely; legs rufo- testaceous ; entire body beneath paler than above. Length 9 mm. ; .36 inch. A much more robust species than any of this group and with the thorax of larger area relative to the elytra. A specimen in the LeConte cabinet, which I have no doubt is the male, has a rather more slender form, the sides of thorax sinuate in front of the hind angles, which are consequently more slender and divergent. Its color is slightly darker. These differences, in view of the opposite sex of the specimens, seem purely sexual and not specific. Occurs in Canada and Oregon, S . C. hyperboreus Gyll. — Moderately elongate, depressed, piceous brown, moderately shining, antennsE and legs ferruginous; surface very sparsely pubes- cent ; antennse short, joints 4-10 as wide as long ; head slightly convex at middle, sparsely punctate; thorax as broad as long 9 > or a little longer % ; scarcely narrowed in front, sides regularly arcuate in front of the hind angles which are slender, divergent, and with a short carina; surface shining, sparsely punctate, median line vaguely impressed ; elytra wider than the thorax, oblong oval, widest at middle, humeri rounded, disc rather depressed, finely striate, strife indistinctly punctate at middle, intervals flat, sparsely punctate; prosternum sparsely punctate at middle, densely and finely at the sides, the lobe moderately prominent, arcuate in front, limited behind by a transverse impression, propleurse densely finely punctate, with coarser punctures intermixed, rather opaque, dis- tinctly pubescent; metasteruum sparsely punctate; abdomen closely punctate with coarse and fine punctures intermixed, and with fine brownish pubescence. Length 6.5 — 8 mm. ; .26 — .32 inch. This species is very nearly as depressed as those of the squalidus group. It is paler in color than Sanborni, and without the faint metallic lustre of that species and differing also in the color of the antennae. This species is known from Lapland, Siberia, Kamtschatka, and on our own continent in Alaska. C’. $$anborui Horn. — Oblong, moderately convex, piceous black, moder- ately shining, sometimes with a faint bronze surface lustre, very slightly pubes- cent; autennfe slender, feebly serrate, joints all longer than wide, iiasal joints 6 GEO. H. HORN, M. D. nifo-testaceons, the outer joints piceous ; head si>arsely punctate; thorax longer than wide, not narrowed in front, widest at middle, sides feebly arcuate, sinuate in front of the hind angles, which are slender, acute, distinctly divergent and carinate above, di,sc moderately curved, the median line vaguely impressed from base to apex, basal incisures distinct; surface sparsely finely punctate: elytra oblong oval, widest behind the middle, humeri oblique, disc striate, strise dis- tinctly punctured, intervals flat, sparsely punctate, but more coarsely than the thorax ; jn-osternal lobe moderately prominent, the border distinctly beaded, a transverse impression posteriorly, coarsely punctate in front, more finely and sparsely toward apex, punctuation at sides denser and intermixed, propleurte rather densely punctate and more opaque, with coarser and fine punctures inter- mixed ; epipleurre jiale; metasternum and abdomen rather densely punctulate with coarser punctures intermixed ; legs rufo-testaceous, tarsi darker. Length 5,5 — 7 mm.; .22 — .28 inch. The hind angles of the thorax at tip, the epipleurae of the elytra and a narrow border of the under side of thorax are usually rufes- cent. The median line of the thorax, although feeble, is distinctly impressed from base to apex ; all the strite of the elytra are punctate. Occurs in the White Mountain region of New Hampshire, where it was first collected by Mr. F. G. Sanborn, and since by Blanchard, Henshaw and others. barbatiis Sahib. — Oblong, moderately convex, piceous black, moderately shining, sparsely clothed with short, inconspicuous, brownish pubescence; an- tenn® slender, feebly serrate, piceous, the two basal joints pale; head rather coarsely punctate, front triangularly flattened, the middle of the triangle elevated in an umbone; thorax longer than wide, very little narrowed in front, sides feebly arcuate, sinuate in front of the hind angles, which are slender and slightly divergent, carina well marked, but short; disc convex, a median impression reaching the base and very nearly the apex ; surface moderately coarsely punc- tate in front and at sides, smoother at middle and near base; elytra oblong-oval, wider slightly behind the middle, humeri rounded, disc convex, deeply striate, strire punctate, intervals convex, moderately closely punctate; prosternum trans- versely Impressed, rather finely punctate behind the groove, very coarsely in front, the lobe moderately prominent, subtruncate; propleurje opaque, slightly rugulose, coarsely sparsely punctate; epipleurte pale ; abdomen closely punctate with coarser punctures intermixed, especially near the sides; legs rufo-testace- ous, the tarsi piceous. Length 6.5 mm. ; .26 inch. Very close to Sanborni, and possibly only an Arctic form of it. The pubescence of the prosternal lobe seems to have been rather exaggerated in importance and extent, as all the species of the pres- ent and the ahbreviatus groups have a slight pilosity in that portion not by any means dense, and often lost by abrasion. I owe to Dr. Sahlberg the privilege of examining a typical speci- men. Occurs in the vicinity of St. Lawrence Bay extending to Port ( 'larence on the American coast. NORTH AMERICAN COLEOPTERA. Group ABBREVIATUS. Prosternal sutures straight, nearly parallel. Maxillary palpi moderate in length, the last joint triangular, truncate at apex. Legs not long, tibiie not spinulose externally, terminal spurs small. Thorax with median line more or less impressed, the basal incisures feebly distinct, hind angles, at most, but little everted, the carina not long. Surface pubescent. Body winged. The group here defined is with difficulty separated by description from the one preceding, but the more convex form, pubescent sur- face and less prominent hind angles seem sufficient. The species composing the group occur in the Arctic regions of both continents, extending southward in the more northern jiortions of the temperate region, and along the mountain ranges in the higher altitudes still more to the south. In consequence of the wide distribution of the species and the varied climatic influences to which they are subjected, a great amount of variation has been produced. This range of distribution is from Labrador on the east to northern California on the west, and in the centre of the continent extending southward along the Rocky Moun- tains to New Mexico, thence northward in every part of British America to the extreme of the Alaskan peninsula. In the great quantity of material examined I have not been able to separate more than three species : Scutellura conspicuously clothed with pale pubescence, that of the elytra some- what scale like. Thorax narrowed in front in its apical two-thirds, sides often obtusely suban- gulate in front of the angular sinuation ; elytra with a denser spot of pubescence near the apex abbreTiatiis. Thorax arcuate near the apex only, the sides thence nearly straight ; elytra without spot of denser pubescence near tip impressicollis. Scutellum sparsely punctate and smooth, with scarcely any pubescence ; surface simply sparsely pubescent; thorax usually very sparsely punctate, the median impression very indistinct lioctiirniis. C. abbreviatus Say. — Oblong, moderately convex, piceous, with greenish bronze surface lustre, sparsely clothed with yellowish cinereous pubescence, somewhat scaly in appearance, forming a conspicuous elongate space on the ely- tral declivity ; anteun® feebly serrate, either entirely piceous, or with the basal joints paler; head coarsely not closely punctate, the frontal margin scarcely distinct from the clypeal ; thorax slightly broader than long, narrowed in front, sides scarcely arcuate, but obtusely subangulate behind the middle, then sinuate in front of the hind angles, these acute but not slender, scarcely divergent, cari- nate ; disc convex, with a median impression usually extending from base to apex and deeper behind, ba.sal incisures feeble, surface shining, moderately 8 (>EO. H, HORN, M. D, closely, not coarsely punctate, pubescence somewhat brownish ; scutellum rather densely clothed with paler yellowish hairs ^ elytra a little wider than the thorax, widest one-third from base, humeri rounded, sides arcuate, gradually narrowed in apical two-thirds, but obtuse at tip; disc convex, striate; strife all punctate, intervals flat, moderately closely and finely punctate; body beneath piceous, finely fulvo-pubescent, epipleurm usually paler; prosternum sparsely punctate at middle, at sides intermixed and finely pubescent, the lobe very coarsely punc- tate, moderately prominent; propleurm o])aque, finely and closely punctate metiisteruum moderately closely punctate with intermixed punctures; abdomen very finely and closely punctulate, the punctures unequal; legs rufo-testaceous, the femora usually darker. Length 5.25—6.5 mm. ; .21 — .26 inch. 'riiis species varies in color from piceous black to brown, the elytra being often quite pale. It may also vary in the form of the sides of the thorax, the subangulation being scarcely evident in some (lacmtris), but the thorax is always narrowed in its apical two-thirds. The strife of the elytra may vary in sharpness, and their punctures are sometimes scarcely evident on the disc. The spot of pale pubescence near the apex is quite characteristic, and its distinctness is not due to the abrasion of the rest of the sur- face. In well preserved specimens the greater portion of the elytral pubescence is finer and more brown, consequently less distinct. No special sexual characters have been observed. (Occurs from Nova Scotia westward through Massachusetts, New York, Canada, Hazleton, Pa. (Dietz), to Oregon and Alaska. C. iiiiprcssicollis Maun. — Oblong, moderately convex, piceous or brown- ish, the elytra paler, surface slightly feneous, the pubescence sparse, pale brown- ish, rather dense and fulvous on the scutellum; antenufe feebly serrate, piceous. the basal joints paler ; head coarsely, moderately closely punctate, the frontal margin scarcely elevated ; thorax scarcely wider than long, sides nearly straight, arcuately narrowed near the front, a faint trace of a sinuation near the ungles, these acute, scarcely at all divergent; the carina feeble, basal incisures distinct: disc convex, the median channel distinct from base to apex ; surface moderately closely punctate and (for this group) rather coarsely, pubescence fulvous ; scu- tellum rather closely pubescent; elytra oblong-oval, widest near the middle, the humeri rounded; disc convex, moderately deeply striate, strife all punctate, in- tervals flat, rather closely punctate and posteriorly slightly asperately ; body beneath piceous, finely pubescent and subopaque, epipleurfe paler; prosternum sparsely punctate, more coarsely in front and more finely at the sides ; propleurte opaque, with dense fine punctures, with coarser intermixed ; metasternum finely indistinctly punctate, punctuation double; abdomen densely finely punctate, with coarser punctures intermixed at the sides; legs rufo-testaceous. femora darker. Length 5 — 6 mm. ; .20 — .24 inch. This species superficially resembles abbreviatus, but the form of the thorax and the absence of the spot of pubescence near the apex will NORTH AMERICAN COLEOPTERA. 9 distinguish it. It will be observed in abhreviatus that the sides of the prosternum have a well marked, fine silken pubescence, but in this there is no such character. In one of the specimens before me the elytra are paler at apex. While I have not seen a type of this species I am quite sure that the forms examined are similar to the unique described by Manner- heim. Occurs in Alaska, Oregon, Hudson’s Bay Territory and Colorado (rare). C. noctnrnus Esch.— Oblong, moderately convex, color variable, surface shilling and with slight aeneous lustre, sparsely pubescent; antennae feebly ser- rate, piceous, the basal joints often paler; head coarsely, not closely punctate, frontal border feebly elevated ; thorax as wide as long, slightly narrowed in front, sides arcuate, widest at middle, a slight sinuation in front of the hind angles, these feebly everted, distinctly carinate, disc moderately convex, median impression feeble, rarely visible in front of the middle; surface finely, sparsely punctate; elytra oblong, a little wider at middle than the thorax, humeri ob- tusely rounded, striate, striae all punctate, intervals flat, or slightly convex near the base, sparsely finely punctate; scutellum sparsely punctate, scarcely at all pubescent; body beneath paler than above, the epipleurae especially so; proster- num very sparsely punctate, even on the lobe, sparsely cinereo-pubescent at the sides, the lobe moderately prominent; propleune opaque, closely and very finely punctate with coarser punctures intermixed ; metasternum and abdomen with fine, indistinct punctures, moderately closely placed, with slightly larger punc- tures intermixed; legs rufo-testaceous, femora always darker. Length 4 — 5.5 mm. ; .16 — .22 inch. A variable species, widely spread over the northern part of the continent, and with an unnecessary amount of nomenclature, the result of local or climatic variation. A few varieties seem to deserve mention. Var. noetvrniis Esch. — Larger in size, piceous black, with teneous surface lustre. The double punctuation of the abdomen scarcely evident, except at the sides. The hind angles of the thorax are not paler than the disc. Alaska, Oregon, California, Nevada. Var. lucidulus Mann. — Smaller than nocturnus, and with rather paler surface and less distinct leneous surface lustre. The hind an- gles of the thorax are usually paler. The punctuation of the under side of body is more distinct, and its double character more evident. Of this form fallax Mann, and vestitus Mann, are merely individual variations. Alaska, Hudson’s Bay, New Hampshire. Var. bicolor Esch.— Still smaller, the hind angles of the thorax and the elytra castaneous, with very feeble metallic surface lustre. TRANS. AM. ENT. SOC. XVIII. (2) JANUARY, 1891. 10 GEO. H. HORN, M. D. Punctuation of under side coarser, its double character very evident. Of this scarificatus and limhatus Mann, are feeble varieties, and pi- cescens Lee. a synonym. Alaska, Oregon, Hudson’s Bay, Dacota, Idaho, Utah, Montana, Colorado, New Mexico, Lake Superior, Canada, Labrador, New Hampshire. On comparing these forms with abbreviatiis and impressicollis, it will be observed that the vestiture is finer and sparser, the scutellum nearly glabrous. The thorax is always more sparsely and finely punctured. The form is also less convex and more elongate. Candeze states (Mon. iii, p. 68) that riparius Fab. occurs in the polar regions of our continent. I have not seen any specimens that I am willing to refer to that species, although some of the forms of iuciduhis have the dorsal striie so feebly punctured that they might l)e considered smooth. The study of the material before me leads to the thought that all the species from the Arctic regions of both continents need a renewed study with a larger number of specimens than seems to have been used. Group SQUALIDUS. Prosternal sutures straight and parallel, or very slightly conver- gent posteriorly. Maxillary palpi not prominent, the terminal joint triangular. Legs slender and moderately long, the tibiae not spinu- lose, the terminal spurs small and inconspicuous. Form oblong, much depressed ; surface opaque, densely punctured, sparsely pubes- cent. Body distinctly winged. This group is represented in our fauna by three species, and a fourth (depres-nis) from Siberia should probably be referred here. The flattened form and opaque surface are repeated in the driaialus series, but these have the strongly arcuate prosternal sutures. The three species are as follows ; Antennfe and legs always pale; under side of body finely pubescent with longer scale-like hairs sparsely scattered sqiialitlus. Antennae and legs piceous, sometimes the tibije are pale; vestiture of under side uniform. Surface very opaque liiiiebris. Surface slightly aeneous plaiiatus. C’. squalidus Lee. — Oblong, piceous black, opaque, sparsely clothed with very short brownish pubescence, with silken yellow sparsely intermixed : head coarsely, not closely punctate : antennse not reaching the hind angles of the thorax, feebly serrate, joints all longer than wide, the eleventh but little longer than the tenth ; thorax longer than wide, distinctly narrowed in front, sides regularly arcuate, sinuate in front of the hind angles, these slightly divergent, NORTH AMERICAN COLEOPTERA. 11 acute, distinctly carinate; surface moderately closely, but not densely punctate^ very evidently lonfiitudinally strigose ; disc feebly convex, a distinct basal in- cisure opposite the fifth stria; elytra slightly wider posteriorly than the thorax, humeri oblique, sides feebly arcuate, more so in the J ; disc sub-depressed, striate, striae punctured, more coarsely at sides, especially near the humeri; in- tervals flat, rather closely punctate; prosternal lobe long, its apex with a feebly beaded edge and without a transverse impressed line posteriorly ; surface coarsely, not closely punctured, feebly pubescent, propleurse opaque, coarsely sparsely punctate and distinctly pubescent; metasternum and abdomen sparsely coarsely punctate, with extremely fine punctuation closely placed between them, the vestiture of pale brown, fine pubescence with intermixed golden scale-like hairs. Length 7.5 — 8.5 mm. ; .30 — .34 inch. The male is more slender and parallel than the female, but shows 110 other differences. Occurs in California at San Jose and vicinity. C. funebris Cand.— Oblong, depressed, black, opaque, finely pubescent; legs piceous, sometimes with the tibise paler; head coarsely and moderately closely punctate; antennae piceous, feebly serrate, the joints all longer than wide; maxillary palpi not prominent, the last joint triangular; thorax a little longer than wide, scarcely narrowed in front, widest at middle, sides regularly feebly arcuate, sinuate in front of the hind angles, which are acute, slightly divergent and with a short carina; disc feebly convex, a distinct incisure each side of base; surface very densely punctured and without strigosity; elytra a little wider than the prothorax, the sides nearly parallel, narrowed at apical third, striate, strife punctured, intervals flat, closely punctate and quite rugous at base; prosternal lobe moderately prolonged, its edge distinctly beaded and with a deeply impressed marginal line and another transverse line of variable distinctness posteriorly, coarsely and closely punctate in front of the transverse line, more finely posteriorly; propleur® very opaque, very scabrous ; metaster- num and abdomen closely finely punctulate, but not opaque, finely cinereo-pu- bescent. Length 7.5 — 8.5 mm. ; .30 — .34 inch. This species is more opaque and blacker than either of the other species, while the punctuation of the thorax is dense and simple, not strigose. The sculpture of the metasternum shows but few coarser punctures and these near the middle, while the abdomen is entirely free of them. The legs may be entirely piceous, or have the tibise somewhat paler. There is absolutely no surface lustre in this species. Occurs in California and western Nevada. C. planatus Lee.— Oblong, nearly parallel, depressed, black, with faint bronze tinge above, beneath opaque; antenufe black, a little longer than the head and thorax, feebly serrate, joints all longer than wide; head coarsely and moderately closely punctate; thorax distinctly longer than wide, widest slightly behind the middle, not narrower in front, sides feebly arcuate, sinuate in front of hind angles, which are slender, acute and slightly divergent, distinctly cari- nate ; disc feebly convex (basal incisures distinct), coarsely, not densely punctate. 12 GEO. H. HORN, M. D. except near the front angles, punctures slightly strigose; elytra scarcely wider than the thorax, parallel or slightly wider behind 9- humeri rounded; disc striate, strite punctured, intervals flat, transversely wrinkled, irregularly triseri- ately, subinuricately punctate ; prosterual lobe moderately prominent, the edge with distinct bead, a transverse impressed line posteriorly in front of which the lobe is densely coarsely punctate, then for a short distance sparsely punctate, followed by a coarse, denser punctuation, with finer punctures intermixed; metasternum coarsely punctate, closely near middle, more sparsely laterally, the intervals finely closely punctate; abdomen closely, finely punctate, with scat- tered larger punctures more numerous in front and on the apical segment. Length 7.5 — 10 mm. ; .30 — .40 inch. In well preserved specimens the pubescence of the upper surface is short and inconspicuous; beneath very fine cinereous or fulvous. This is the only species of the group with a faint bronze surface, consequently less opaque than squalidvs or fmiebris. AVhile closely related to the latter the punctuation of its upper surface is less dense, the antennae longer, and the punctuation of the under surface more intermixed and coarser. The name given to this species was previously made use of by Eschscholtz, but that being identical with hyperboreus, and the name consequently suppressed, there seems to me no great objection to its use for the present species. Occurs in western Pennsylvania, New York and Canada, White Mountains (Austin). Group STRIATULUS. Prosterual sutures arcuate and convergent behind. Maxillary j)alpi not prominent, the last joint elongate triangular. Thorax densely punctured and opaque, with, at most, a smooth median line, base without incisures, carina of hind angles short. Elytra striate, equally at the sides. Legs slender, the tibial spurs small. Form depressed. Body winged. The only species composing this group resembles a diminutive planatm, but differs from that group by the form of the prosterual sutures. The peculiar sculpture of the thorax in the choris and Melsheimeri groups will prevent its being placed with them, the perplexm series is convex, shining and ornate, while the tumescens group is convex without ornamentation. C. striatulus Lee. — Obloug, subdepressed, piceous black, opaque, finely cinereo-pubescent; legs pale, the femora darker; antennae slender, black, feebly serrate; head feebly convex, densely rugosely punctate; thorax a little wider than long, narrowed in front, sides arcuate, slightly sinuate in front of the hind NORTH AMERICAN COLEOPTERA. 1 lo angles, which are stout, slightly everted, and with a short carina ; disc feebly convex, densely finely punctate, the median line usnally smooth, but not always ; elytra as wide as the thorax, humeri obtuse, sides nearly parallel for two-thirds then arcuate to apex ; disc rather fiat, striate, equally from middle to sides, strife punctate, intervals feebly convex, densely and finely punctulate, the surface opaque; prosternum moderately closely punctate, more densely and finely at the sides, the lobe short and subtruncate, the transverse impression distinct ; pro- pleni’se closely finely punctate, not opaque ; metasternum and abdomen densely punctate, a little more closely than the propleurse. Length 3 — 4 mm. ; .12 — .16 inch. An easily known species by the group characters alone. In some specimens the basal joints of the antenne are somewhat paler, but these specimens have the under side somewhat paler also, and are probably less mature. The distribution of this species is rather remarkable. Originally described from the Lake Superior region, it extends westward to Oregon (Wickham) and northern California, eastward to Ohio (Dury) and Allegheny, Pa (Hamilton). Group CHORIS. Prosternal sutures arcuate and convergent posteriorly. Maxillary palpi moderately prominent, the last joint elongate triangular. Form convex. Elytra deeply striate, more or less ornate. Thorax roughly granulate, the median line usually finely elevated and smooth ; sur- face more shining. The species of this group seem naturally to fall together by the very rough sculpture of the entire surface of the thorax. In the dermestoides group the thorax is somewhat granulate in front, but comparatively smooth posteriorly. To this group belong pxdchelhis and sahxdieola, probably also curtus and alysidotus of the European fauna. The species known to occur in our fauna may be separated in the following manner : Apical margin of thorax truncate at middle. Form gibbous, strongly arched when viewed laterally; carinse of hind angles short ; entirely pale above cleliinibis. Form normal, not very convex; cariufe of hind angles long; color black, or- nate with yellow. Antennae with three basal joints pale yellowish testaceous; legs always entirely pale clioris. Antennse piceous, very little, if at all, paler at base; legs with the femora at least fuscous or piceous. Elytra gradually attenuate in their posterior third.. exiguus. Elytra not attenuate, ape.x obtuse oriiatiis. Apical margin of thorax arcuate at middle, slightly prolonged over the head and somewhat elevated Cliciillatus. 14 GEO. H. HORN, M. D. €. «lellinibi« n. sp.— Oblong, narrowed posteriorly, rather strongly arched, when viewed laterally, convex ; color above ochreous, the thorax ferruginous, the head darker, elytra with vague fuscous spaces, often absent, beneath piceous or brown, the last ventral segment and prosternal lobe pale; antennje entirely pale, the outer joints scarcely longer than wide; head flat, granular; thorax disti!ictly longer than wide, sides slightly arcuately narrowed from middle to apex, nearly straight posteriorly, angles not divergent, the carina well marked, but short, disc convex, the median line finely elevated and smooth ; surface closely granular, not forming strig® ; elytra acutely oval, narrowed almost from the base, humeri obliquely rounded; disc deeply striate, stri® rather wide, coarsely not closely punctate, intervals convex, flatter at apex ; surface submu- ricately punctate; prosternum closely and rather roughly punctate, distinctly transversely impressed in front, the lobe moderately prominent, but obtuse ; pro- pleur® closely punctate; metasternum rather short, coarsely and closely punc- tate; abdomen densely submuricately punctate, becoming granulate on the last two segments; legs pale yellowish testaceous. Length 4 — 5 ram. ; .16 — .20 inch. This species is remarkable in its sharply arched form when viewed laterally, as well as by the pale color of the surface. The elytra are usually pale ochreous, but some specimens have a fuscous space on the declivity of broadly crescentic form extending forward by its outer angle parallel with the margin. The carina of the hind angles is short, i.e., extending but little in front of the angles themselves, while in all the other species of the group it extends nearly or quite three-fourths to the ajiex. Specimens were sent me many years ago by Mr. F. G. Sanborn, collected by him in some numbers at Truro, Mass., a town on the Cape Cod peninsula. It should occur in other places on the Atlantic coast. C. choris Say. — Form moderately elongate, distinctly narrowed posteriorly, moderately convex, black, opaque, sparsely clothed with cinereous or golden hairs, each elytron with an angulate sub-basal band, which extends to the humeri, another transverse posteriorly yellow; anteun® slender, feebly serrate, piceotis, the three basal joints pale yellowish testaceous; head feebly convex, coarsely and closely granulate; thoi-ax very little longer than wide, sides feebly arcuately narrowed in front, behind the middle nearly straight, or with a very feeble sinuation in front of hind angles, these divergent, the carina long, ex- tending fully three-fourths to apex ; disc convex, a smooth, median, elevated line; surface rather coarsely and closely granulate, elytra widest in front of middle, thence gradually narrowed to apex, humeri obtuse ; disc deeply striate, stri® punctured, intervals convex, flat near apex, roughly, not closely punctate and somewhat wrinkled ; prosternum closely punctate, but smoother in front; two feeble transverse grooves in front, lobe moderately prominent, obtuse; pro- pleur® more densely punctate, but not opsique; nietasternum and abdomen densely and moderately coarsely punctate, but somewhat shining; legs pale rufo-testaceous, the femora rarely slightly darker. Length 3 — 5 mm.; .12 -.20 inch. NORTH AMERICAN COLEOPTERA. 15 The extent of yellow color in the bands is variable so that the elytra may have more of that color than black, or vice versa. Speci- mens of the former were those seen by Say. The normal style of marking consists of a rather broad post-basal band with very sinuous edges, crossing the suture and reaching the lateral margin ending a broad extension to the humeri, behind the middle a transverse band crossing the suture where it is broadest, not reaching the side margin, with a posterior extension along the suture. The style of ornamen- tation seems intermediate between that of exiguus and ornatus. The elytra at tip have often a narrow pale border. Occurs from the Middle States region westward to Indiana, and south to District of Colundiia. A specimen collected by myself at Fort Tejon does not appear to difler in any respect from those found in the more eastern regions. t-. exiguus Rand. — Moderately elongate, narrowed posteriorly, convex, black, opaque ; elytra ornate with yellow ; antennae slender, piceous, three basal joints fuscous, paler beneath : head flat, densely granulate, sparsely clothed with short whitish pubescence ; thorax a little longer than wide 'J, , or as wide as long 9; sides feebly arcuately narrowing to the apex in front, posteriorly parallel with a slight siuuation in front of the angles, which are acute and slightly di- vergent, the Carina long, extending fully three-fourths to apex; disc convex, closely granulate, the median line smooth and distinctly elevated ; surface sparsely pubescent, more conspicuously at the hind angles; elytra widest a little behind the humeri, then gradually narrowed to apex, humeri obtuse; disc rather deeply striate, but less so near the apex, striaj punctate, intervals slightly convex at base only, rather closely submuricately punctate, but smoother at apex, sparsely cinereo-pubescent; prosteruum moderately closely punctate, but smoother in front between the two transverse grooves, the lobe modeiate, but obtuse; pro- pleurfe subopaque, densely punctate ; metasternum densely and rather coarsely punctate; abdomen less closely and less coarsely punctate, last segment rufes- cent; femora and tai-si piceous, the tibiae pale. Length 2.5 — 3 mm.; .10 — .12 inch. This species has been the cause of some confusion, in which every author who has treated of our Elateridte has had part. Described originally by Randall, in 1838, under the above name it received a second (guttatulus) from Mesheimer in 1845. In 1853, Dr. LeConte, in his “ Revision of the Elateridie,” placed exiguus and guttatulus, in part, in synonymy with imlchellus. When the Melsheimer collection became accessible to him it was observed that two species had been confounded, each represented by a single poor specimen, one representing the present species, the other it was thought might prove to be quadripustulatus of Europe accidentally introduced in the cabinet. This latter specimen bore the typical 16 gp:o. h. horn, m. d. label, ami was therefore assumed to be the type, notwithstanding the fact that the very good description given by Melsheiiner points clearly to exigmis. It is, therefore, without hesitation that I suppress gut- iatnlus, absolutely, as a synonym, and for the species erroneously so determined by LeConte the name Melsheimeri is proposed, and will be found in its proper group. Ur. Candeze simply followed in the lead of LeConte. A few months ago (“ Entomological News,” 1890, p. 9) I continued the same error through not having imldiellm for comparison. The sahu- licola which had been sent me instead, serving alone for comparison, led me to believe that our specimens fully met the requirements noted by Fauvel (” Revue Ent.” 1889, p. 142). On comparison of exiguus with puleheUus, it will be observed that the former is more slender and convex, the elytral stride more dis- tinct at apex and the elytra at tip piceous without the bifid space seen in the other. The three basal joints of the antennae are pale rufo-testaceous in pulchellus, piceous in exiguus, although paler be- neath. The femora are also paler in the former species. There seems to be a closer resemblance between pulchellus and ehoris. They have similarly colored antennte and legs, but the elytra are more roughly sculptured, the strite deeper at apex, and the bifid spot absent in ehoris. Occurs in the New England and Middle States; Massachusetts (Blanchard) to District of Columbia (Ulke). C. oriiatiis Lee. — Oblong, moderately convex, not attenuate posteriorly, black, opaque; surface finely ciuereo-pubescent ; elytra either ornate, as in pul- chellus, or with merely two small spots posteriorly or entirely black ; antenuse slender, feebly serrate, entirely piceous ; front flat, densely granulately punctate ; thorax a little variable in form, as wide as long ?, or a little longer than wide "J, , narrowed in front, widest usually at or near the base, sides feebly arcuate in front, behind the middle nearly straight and parallel, or with a faint sinuation in some males, the angles not divergent, the carina extending nearly three- fourths to apex, disc convex, the median line finely elevated and smooth ; surface opaque granulate, the granules elongate and forming short strigae posteriorly; elytra parallel, arcuately narrowed at apical third, humeri obtuse ; disc moder- ately deeply striate, striae punctured, intervals flat, slightly convex, at base in male, roughly punctate, more or less transversely wrinkled and rugulose, espe- cially near the base; prosternura rather coarsely and closely punctate, especially in front, two transverse impressions anteriorly, the lobe moderately prominent, but obtuse; propleurae closely punctate, but not opaque; metasternum densely and rather roughly punctate ; abdomen densely punctate, less coarsely than the metasteruum. Length 3—5 mm. ; .12— .20 inch. NORTH AMERICAN COLEOPTERA. 17 The males are more slender and rather more coarser than the females, the thorax a little longer than wide and with a faint sinua- tion in front of the hind angles, which are, however, not divergent. There is considerable variation in color in the specimens before me, and three varieties may he indicated. Var. ornatus Lee. — The elytra have two yellow spaces. The an- terior is transverse, post-basal, of irregular form, widest externally, but not extending to the humerus nor margin. The posterior is behind the middle, transversely oval, not reaching the side nor the suture. The femora are piceous, the tibise and tarsi usually paler. Var. colon Horn. — Here the elytral markings are reduced to a small round spot on each side in the position of the posterior spot of the jireceding variety. The legs may be as in ornatus, or entirely piceous. Var. rncerens. — Entirely black, without elytral markings. The legs are nearly always piceous. Occurs in California from San Diego northward in the central valley, as well as along the coast region to Oregon (Blanchard). C. ciicullatns n. sp. — Elongate oval, rather broader in proportion to its length than usual in the genus, moderately convex, black; elytra with faint bronze lustre; thorax cinereo-puhescent near the hind angles; elytra with ex- tremely fine and short flavo-cinereous pubescence ; antennae slender, feebly ser- rate, entirely piceous; head flat, closely punctate; thorax scarcely longer than wide, sides straight posteriorly, gradually arcuately narrowed from middle to apex, hind angles not divergent, the cariua extending in front of middle, apical margin arcuate and prolonged over the head, deejtly sinuate near the front an- gles; disc convex, without smooth median line; surface very coarsely granulate but somewhat smoother on the declivity and near the hind angles ; elytra with sides parallel, arcuately narrowed at apical third; apex obtuse, humeri obtuse; disc moderately convex, striate, strife punctate, intervals slightly convex in their entire extent and closely punctulate ; prosternum granulate in front, rather finely punctate posteriorly, a faint transverse impression in front, the lobe short and obtuse; propleurfe more finely and closely punctate than the sternum ; met- asternuin a little more coarsely punctate; abdomen rather more finely and densely ; legs piceous, the tibife and tarsi paler. Length 3.5 mm. ; .14 inch. This species is easily known by the form of the apical border of the thorax of which the middle forms a short lobe partly concealing the head from above. On each side of this lobe is a rather deep sinuation causing the front angles to be more acute and prominent than usual. Specimens have been examined from the Indian Territory ; Co- lumbus, Texas (Schwarz), Utah (Ulke). A specimen has been seen labeled Ohio, but the locality seems doubtful. TRANS. AM. ENT. SOC. XVIII. 13) JANUARY, 1891, 18 GEO. H. HORN, M. D. Group MELSHEIMERI. Prosternal sutures arcuate and couvergeut posteriorly. Maxillary palpi not promiiieiit, the last joint elongate triangular, the apex rounded. Thorax asperate, or subgranulate in front, becoming gradually quite smooth posteriorly, the base without incisures. Ely- tra striate ; tibiae slender, spurs small ; surface usually shining, elytra often ornate. Body winged. A group of small species standing naturally betw^een the choris and perplexus series. Its essential character is in the sculpture of the thorax, the anterior portion being quite roughly or more densely sculptured, and the basal portion quite smooth. Some curious sexual peculiarities have been observed in some of them, of rare occurrence in Elateridae, but by no means rare in Eucnemidae, consisting of tu- bercles or pubescent spots on the first two ventral segments. The elements composing the group are by no means homogeneous, and might be again divided as the last three species have not that very marked difference in sculpture of the thorax so well shown in the others. As a whole, the group is known from the striatulus series by its more convex form and the evident inequality of the thoracic punctuation ; from the choris series by the opaque, granular thorax of these ; the j)erplexus series has usually a sparsely punctate thorax, and in any event the punctures are equal and equally disposed. The following species are known to occur in our fauna : Prosternal sutures widely double, smooth and grooved in nearly their entire length ; thorax simply emarginate at apex when seen from above. Antennae and legs pale; anterior tibiae of male not broader than in female, the first ventral 'J, with a flattened space at middle enclosing a tubercle Melsliei meri. Antennae piceous, tip of first and the second and third joints paler; legs j)ale, femora darker ; anterior tibiae of male nearly twice as broad as in the female, the first ventral 'J, scarcely flattened, but with an oval hairy spot quad rig uttatus. Antennae piceous, paler at base; legs pale, femora piceous; anterior tibiae of male not broader, the first and second ventrals of male with a tu- bercle near the posterior border vatiriiius. Antennae as in qiiadriguttatus, legs similar; anterior tibiae of male broader than in female, but less marked; first ventral of male gibbous be- tween the coxae, rather suddenly declivous posteriorly and fringed with longer hair dermestoides. Prosternal sutures very narrowly double, not grooved. Carina of the hind angles of thorax extending to or beyond the middle of the thorax. NORTH AMERICAN COLEOPTERA. 19 Form subdepressed; thorax distinctly rugulose iu front; posterior coxal plates obliterated externally. Thorax simply emarginate in front; no ventral sexual characters in either sex dispersiis. Thorax sinuate each side at apex, the middle somewhat elevated and pro- longed over the head ; second ventral of 9 with oval pubescent spot graersiis n. sp. — Oblong, moderately convex, piceous black, feebly shining, sparsely and finely cinereo-pubesceiit, each elytron with a faint humeral and subapical yellow spot, or without any ; autenuse slender, feebly serrate, en- tirely piceous, or with joints 2-3 pale; head convex, sparsely asperately punc- tate; thorax a little wider than long, apex emarginate, sides parallel for a short distance posteriorly, thence arcuately narrowed to the front, the hind angles NORTH AMERICAN COEEOPTERA. 21 broad, but acute; tbe carina extending two-thirds to apex, disc convex, median line smooth in front, surface asperately punctate in front, sparsely punctate pos- teriorly; elytra as wide at base as the thorax, but evidently narrowed from the obtuse humeri, disc striate, striae finely puuctate, intervals slightly convex, finely moderately closely punctulate; prosternum not closely punctate, a feeble trans- verse impression in front, lobe obtusely prominent, coarsely and closely punc- tate, the sutures very narrowly double, but not at all excavate, propleune less shining, very minutely and densely punctulate; metasternum and abdomen densely and finely punctulate ; legs testaceous, the femora darker. Length 2.25 mm. ; .09 inch. The two specimens before me, which seem to be male and female, exhibit no ventral sexual characters. One % from Washington has entirely piceous antenme, a very faint humeral spot, the subapical more distinct ; that from Nevada has no elytral spots, and the second and third joints of the antennse pale. A third from Nova Scotia, probably representing a distinct species, has the elytral spots well marked as in Mehheimeri, and the three basal joints of the antennse pale. In the absence of a male it is for the present placed with this species. Occurs in Nevada, Washington (and Nova Scotia?). C. gradariiis n. sp. — Obloug, feebly convex, piceous-black, subopaque, faintly bronzed, surface finely cinereo-pubescent, more evidently in the depression near the hind angles; antenme black, slender, feebly serrate; front slightly im- pressed, rather coarsely and roughly punctured ; thorax very little wider than long, narrowed in front, sides posteriorly straight, in front gradually arcuate to apex, apical border sinuate, slightly elevated at middle and prolonged over the head, hind angles broad, but acute, the carina extending two-thirds to apex, disc convex, asperately puuctate in front, more finely and smoother posteriorly; ely- tra as wide at base as tbe thorax, humeri obtuse, sides feebly arcuate, apex ob- tusely rounded, disc striate, strife punctulate, intervals feebly convex, punctulate ; prosternum sparsely punctate, shining, a feehle transverse impression in front, lobe not prominent, obtusely rounded, coarsely puuctate. prosternal sutures simple, without trace of excavation, propleurfe subopaque, densely finely punc- tulate; metasternum and abdomen closely finely puuctate; legs rufo-testaceous, femora darker. Length 2 mm. ; .08 inch. The male shows iio sexual characters on the ventral segments, the female, however, has a finely pubescent, oval spot at the middle of the second segment. This species is the one I had thought identical with dermestoides, but a closer examination shows it to be our equivalent, on this con- tinent, of curtvs of Eurojie. The sinuation of the apical border of the thorax, although sufficiently well marked in comparison with the others of the group, is less distinct than in cncidlatus. The denser silken pubescence of the hind angles of the thorax is rather a con- 22 gp:o. h. horn, m. d. spicuous feature of tliis species. The two specimens before me are precisely alike above and show no traces of pale spots. Collected by IMr. D. W. Coquillett at Los Angeles. tiiiuesceiis Lee. — Oblong, convex, facies robust, piceous-black, with slight feneous surface lustre, sparsely cinereo-pubescent ; antennae either entirely piceons, or with joints 2-3 paler; joints subtriangular from 4-10; head convex, closely punctate ; thorax as wide as long, narrowed in front, sides rather strongly arcuate, sinuate in front of the hind angles, which are acute, slightly divergent, with the Carina extending nearly half to apex, disc convex, the median line smooth, surface moderately closely punctate, a little roughened near the apex only, gradually more finely posteriorly; elytra oval, widest a little behind the middle, humeri obtuse, disc convex, striate, strife punctate, intervals slightly convex near the base, sparsely punctate, more coarsely in front, the lobe obtuse, propleurfe more closely punctate; metasteruum more coarsely punctate; abdo- men more finely and closely punctate ; legs rufo-testaceous, the femora piceons. Length 3 — 4 mm. ; .12 — .16 inch. The prosteriial sutures, while doubled as usual in the group, are very narrow, although in the female they are distinctly wider than in the male. The form of this species is quite that of a diminutive Cardiopho- rus. The sculpture of the thorax does not have that marked rough- ness seen in the preceding species. The posterior coxal plates are not obliterated externally. Occurs on the north shore of Lake Superior (LeConte), upper Canada (Pettit) and New Mexico (Fuller); White Mountains (Blanchard). C. musculus Esch. — Oblong, convex, fscies robust, black, shining, surface distinctly seneous, sparsely pubescent; anteniife piceous, slightly serrate ; head convex, closely, subasperately punctate; thorax broader than long, very little narrowed in front, sides strongly arcuate, sinuate near the hind angles, which are acute, slightly divergent, and with a very short carina, disc convex, median line smooth, surface closely and slightly asperate in front, gradually more finely and s])arsely behind ; elytra oval, widest at middle, humeri rounded, disc convex, striate, less deeply at sides, strife punctate, intervals slightly convex near the base, moderately closely, but finely submuricately punctate, forming transverse ridges near the base; prosternum sparsely punctate, a distinct transverse groove in front, the lohe rather obtuse, propleurae similarly punctate; metasteruum a little more coarsely punctate ; abdomen punctate similarly to the propleuraj, but more densely; legs piceous, the tibife and tarsi paler. Length 2.5 — 3 mm.; .10 — .12 inch. The prosteriial sutures are not at all doubled in this species. The carina of the hind angles of the thorax is here very short and in- conspicuous, and might readily be passed unobserved. The posterior NORTH AMERICAN COLEOPTERA. 23 coxal plates are obliterated externally, the posterior edge being con- fluent with the anterior. Occurs in Alaska. C. tliibius Horn. — Oblong, moderately convex, fuscous, feebly shining, sparsely pubescent, hind angles of thorax paler; antennae slender, scarcely ser- rate, fuscous, the three basal joints paler; head slightly flat, closely subasper- ately punctate; thorax a little wider than long, narrowed in front, sides parallel behind, arcuate anteriorly, the hind angles nearly rectangular, the cariua mod- erate in length, disc convex, the median line smoother, surface closely punctate and somewhat scabrous in front, gradually more smooth posteriorly ; elytra ob- long, sides parallel, arcuate at apical third, humeri obtuse, disc striate, a little less at the sides, strije relatively coarsely punctate, intervals flat, finely and moderately closely punctate; prosternum sparsely punctate, transversely im- pressed in front, the lobe short and obtuse, propleurfe finely and indistinctly punctate; metasternum more coarsely punctate; abdomen very finely and mod- erately closely punctate ; legs pale. Length 2 — 2.5 mm.; .08 — .10 inch. The under side of body is notably paler than the upper, especially on the sternal members and the epipleurte. The posterior coxal plates are obliterated externally. This species has the same general outline of body as in the Mel- sheimeri series, but is more convex. Occurs in Nebraska and Dakota (Ulke). Group PERPLEXUS. Prosternal sutures arcuate and rather strongly convergent poste- riorly. Maxillary palpi moderately prominent, the last joint elon- gate triangular. Elytra moderately deeply striate, ornate with yel- lowish spaces. Form rather slender, convex. Thorax simply punctate, not rugose, the median line not elevated nor smooth, with- out basal incisures. Legs slender, tibial spurs very small. Among the species with arcuate prosternal sutures, those of this group are known by the striate and ornate elytra, with comparatively smooth thorax. The only exotic species known to me as belonging here is quadrijnistulatus Fab. The species are separated as follows : Thorax distiuctly narrowed iu front, at base as wide, or wider than at middle. Antennfe and legs entirely piceous geiitilis. Thorax coarctate at base and apex nearly equally, widest at middle, hind angles slender, slightly divergent. Legs and three basal joints of the an- tennse yellowish testaceous. Elytral humeri obtuse, body with well developed wings, striae scarcely more punctate than the intervals ; each elytron with two yellow spaces, humeral and subapical sestivus. Elytral humeri rounded, body very feebly winged, striae more coarsely punc- tate than the intervals. Each elytron with two yellow spots; thorax wider than long. quadripustulatus. Each elytron with a humeral spot only ; thorax distinctly longer than wide perplexus. 24 (4KO. H. HORN, M. D. Tlie European species is introduced in the table for the comparison of its characters with the two in our fauna most closely allied to it. C’. soiililis Lee.— Moderately convex, piceous, feebly shining, clothed with tine flavo-cinereous silken pubescence, each elytron with an arcuate humeral oblique yellow stripe and a short transverse one behind the middle; antennse slender, ])iceous, feebly serrate, joints all longer than wide; head vaguely longi- tudinally impressed, finely and moderately punctate, slightly scabrous; thorax as broad as long, narrowed in front, sides anteriorly feebly arcuate, nearly straight at basal fourth, the hind angles stout not divergent, tipped with yellow, the Carina extending nearly to middle, but very feeble in front, disc moderately closely finely punctate, the median smooth line very feeble, the pubescence ir- regularly arranged, giving a holosericeous appearance; elytra as wide at base as the thorax, humeri obtusely rounded, disc feebly arcuate, gradually narrowed from base, disc deeply striate, striae closely punctate, intervals convex, densely punctulate, somewhat scabrous near the base; prosternum sparsely punctate, a little more coarsely in front, with two vague transverse impressions, the lobe obtusely rounded with narrowly beaded margin, propleurm a little more closely punctate than the sternum, shining ; metasternum and abdomen a little more coarsely punctate than the prosternum, the apical segment somewhat roughened. Length 3-4 mm.; .12— .16 inch. In the male the form is more slender, and, contrary to what has been noticed elsewhere in Elateridte, the elytral intervals are less convex. The hind angles are also very slightly divergent. The frontal impression may be vaguely triangular. The yellow humeral lunule of the elytra is, in form, vei*y like the same mark in Cicindela. The legs are jticeous, but sometimes the tibite and tarsi are paler. Frotn either of the species of this group this differs in having the thorax broadest at base, the antenme and legs piceous. Occurs in Nebraska (Ulke), Wyoming and Washington (Morrison) C. sestivns Horn.— Oblong, moderately elongate and convex, piceous, basal joints of antennse, hind angles of thorax, legs, a humeral and subapical spot on each elytron yellowish testaceous, surface moderately shining, sparsely pubes- cent; antennte feebly serrate, joints slender; front rather flat, head vaguely punctate and slightly rugulose ; thorax not longer than wide, slightly narrowed in front, widest slightly in front of middle, sides arcuate, distinctly sinuate in front of the hind angles, which are slender, acute and distinctly divergent, the Carina not prolonged, disc moderately convex, not closely punctate, the median smooth line feebly evident posteriorly; elytra as wide at base as the thorax, humeri obtuse, sides feebly arcuate, disc striate, strife punctate, intervals slightly convex, not closely punctulate; prosternum sparsely finely punctate, vaguely transversely impressed, the lobe short and truncate, propleur® more coarsely and punctate than the prosternum at middle, shining; mesosternum punctured simi- larly to the propleui-fe, the abdomen a little more finely. Length 4 — 5 mm. ; .16 — .20 inch. NORTH AMERICAN COLEOPTERA. 25 In this species tlie elytra are colored very like gentilu. The more striking differences between it and the others of the group are suffi- ciently detailed in the table. Occurs in Missouri ; collected by Dr. S. V. Summers, Ohio (Blan- chard). C. perplexiis Horn. — Moderately elongate and convex, piceous-black, shining, sparsely pubescent, three basal joints of the antennse, legs and a humeral spot reddish yellow; antennse slender, feebly serrate; front rather flat, sparsely punctate; thorax distinctly longer than wide, nearly equally narrowed at base and apex, widest a little in front of middle, sides arcuate, distinctly sinuate in front of the hind angles, which are small, acute and distinctly divergent, the Carina distinct, disc convex, sparsely but equally punctate, median smooth line distinct; elytra elongate oval, widest at middle, humeri rounded, the disc striate, strise rather deep and coarsely punctate, the intervals convex, shining and very sparsely punctulate ; prosternum transversely impressed in front, the lobe short and obtuse, surface sparsely finely punctate at middle, more distinctly at the sides, propleura*, shining, a little more coarsely and less closely punctate than the sternum; metasternum a little more coarsely and closely punctate; abdomen more finely than this. Length 2.75 — 3.5 mm. ; .11 — .14 inch. This species resembles that variety of quadripmtvlatus in which the humeral spot alone is present, but it differs in having the thorax very obviously longer than wide, the elytral striie more coarsely punctate, and the intervals smoother. The hind angles of the thorax are sometimes tipped with yellow, but this is by no means frequent. The body is very feebly winged. Occurs in the District of Columbia, where it has been collected abundantly, at times, by Mr. Ulke. Group PECTORALIS. Prosternal sutures arcuate, convergent posteriorly, nearly twice as widely separated at the apical angles as at the coxae. Maxillary palpi not prominent, the last joint triangularly oval. Legs slender, the tibial spurs minute. Form at least moderately convex, body winged. Elytra either not at all striate, or those near the suture alone indicated faintly. Thorax without basal incisures, a smooth median line variably present. This group is equivalent to the second division, A A, indicated in the Monograph of Candeze. Those occurring in our fauna separate very naturally from the exotic forms by having the carina of the hind angles of the thorax short, while in those the carina is pro- longed nearly or quite to the anterior angles. TKANS. AM. ENT. SOC. XVIII. (4) FEBRUARY, 1891. 2G GEO. H. HORN, M. D. The species known to inhabit our fauna may be separated by the following table.

Surface subopaque, the punctuation very distinct, especially on the thorax; color very variable, from yellowish testaceous to piceous, with intermediate maculate forms poctoralis.

C. restrictulus Mann. — Oblong, moderately elongate and convex, piceous, shining, very sparsely pubescent ; antennae piceous, longer than the head and thorax, slender feebly serrate, joints all longer than wide ; head slightly concave, not closely punctate ; thorax slightly longer than wide, widest at middle, slightly narrowed in front, sides arcuate, sinuate in front of the hind angles, which are slender, acute, divergent and carinate, disc convex, finely not closely punctate, the median line faintly smoother ; elytra oblong oval, widest at middle, humeri rounded, disc moderately convex, very faintly striate near the middle, the striae impressed in the basal declivity, at the sides entirely obliterated, surface moder- ately closely punctate, except near the apex ; prosternal lobe short, mouth ex- posed, the sternum moderately convex, sparsely punctate at middle, more closely near the sides, propleurse shining, moderately closely punctate; metasternuni and abdomen similarly punctate, not (dosely nor coarsely ; legs piceous, the tibiae and tarsi sometimes paler. Length 3.5 mm. ; .14 inch. In the male the last ventral segment is bisinuately truncate with a median tooth, the same segment of the female is similarly truncate, but in a less pronounced manner. This species is described in the Monogra])h of Candeze as musculus Mann., but a comparison of the original descriptions will show that Dr. Candeze had restrictulus and not the other before him. Besides, a type of muscuhis is in the LeGonte collection from Mannerheim. The measurement given by Candeze is also incorrect foi' either spe- cies, while its position among the striate species is certainly mislead- ing. The form of the last ventral segment is not found in any other species in our fauna. In habitus the species resembles Oedostethns femoralis, but in the latter the stride are more distinctly impressed, although obliterated at the side, and the claws have the basal half dilated. Occurs in Alaska (Mannerheim, Ulke) and in the White Mountain region of New Hampshire (Blanchard). NORTH AMERICAN COLEOPTERA. 27 obliqiiatiilus Mels. — Oblong, moderately convex, pi ceo us, thorax some- what paler in color, very sparsely pubescent, antennfe and legs testaceous; an- tennse slender, feebly serrate, joints all longer than wide; head sparsely punc- tate ; thorax a little wider than long, slightly narrowed in front, widest at middle, sides regularly arcuate, sinuate in front of the hind angles, which are small, acute, and very slightly divergent, the carina fine, and. when seen from above, directed nearly straight to the front, disc moderately convex, sparsely equally punctate, the median smooth line very faint; elytra slightly wider than the thorax, humeri very little oblique, sides regularly arcuate, widest at middle, disc entirely without striae, more sparsely and finely punctured than the thorax, color piceous, on each elytron an oblique yellowish band reaching the margin, but not the suture, an oval apical spot of variable size also yellow ; prosternum sparsely punctate, and with two transverse impressions, the lobe moderately prominent, but obtusely rounded in front, the border finely beaded, propleurae shining, more sparsely and finely punctate than the sternum ; metasternum minutely and in- distinctly punctate, abdomen more densely and coarsely. Length 2.25 — 2.75 mm. ; .09 — .11 inch. Usually the underside of the body is much paler than the upper, especially in the prothorax and the elytral epipleurie. The color and markings seem to be very constant, and vary but little beyond that caused by varying degrees of maturity. The males have a small, densely punctured space at the middle of the prosternum, usually more pubescent, but never as distinct as in pectoralis. Distributed from Canada aud the New England States southward to Virginia and westward to Iowa. C. pectoralis Say. — Oblong, feebly convex, subopaque, sparsely finely pu- bescent, color variable from entirely yellow to entirely piceous ; antennte slender, feebly serrate, joints all longer than wide, yellowish testaceous ; head moderately closely punctate, front fiat; thorax usually as wide as long, sometimes slightly longer, slightly narrowed in front, widest at middle, sides arcuate, scarcely sinuate in front of the hind angles, which are S7nall, acute, but not divergent, the carina, when viewed from above, turned externally, disc very distinctly and rather closely punctate, the median smooth line usually evident; elytra slightly wider than the thorax, humeri slightly oblique, sides arcuate, disc without strife, surface less distinctly punctate than the thorax; prosternum moderately closely punctate, transverse impression not well marked, the lobe moderately prominent, subtruncate in front, propleurfe- punctate similarly to the sternum ; metasteruum punctate similarly to the prosternum, the abdomen much more finely and densely. Length 1.5 — 3 mm. ; .06 — .12 inch. The males of this species have a small, but densely punctured s]iot at the middle of prosternum from which arises a bunch of longer pubescence. The pubescence is often absent, except in well preserved specimens. This species varies greatly in color, and has been given three names in consequence. These varieties may be de.scribed as follows : 28 GEO. H. HORN, M. D. Y nr. pectoralis iiiiy. — Entirely yellowish testaceous above and be- neath. Specimens often occur with a transverse fuscous fascia behind the middle of the elytra, which extends narrowly along the suture to the apex. This form occurs from Massachusetts to California and Texas. Va.r.futilis Lee. — This does not differ from the preceding variety, except in its smaller size and with apparently a slightly more rugose thoracic sculpture. A subvariety occurs in Arizona entirely piceous. 'fhese latter are the smallest specimens seen (.06 inch). Occurs at San Diego and Owen’s Valley in California, and also in Arizona. Var. inops Lee. — Piceous, elyti’a with an indefinite humeral yellow spot, a short transverse band at middle adjacent to the lateral mar- gin, these two sometimes united along the margin, a subapical yellow space. Specimens often occur with a median discal space of the thorax yellowish. Occurs in California and Washington. Var. . — Entirely piceous, and occasionally with the legs darker than normal. This is known to me from the extreme northwest, Washington, although one from Iowa has merely slightly paler humeri. From the localities given this seems to be the most widely dis- tributed of our species. Synonymy and Bibliography. C’RYPTOHYPNIJS Eseb. § C. littoralis Esch., Tbon.

This genus does not seem to be generally known to collectors, so that but few specimens have ever been sent me for determination. It differs from Cryptohypnus in having the claws abruptly dilated at basal half as shown in fig. 8, pi. 1. The prosternal sutures are arcuate, but in a less degree than in the species of Cryptohypnus with sutures. Oe. femoralis Lee.. Revis. Elat. p. 489. This is the only species known. It greatly resembles C. restrictuhis, having the stride of elytra feebly distinct on the disc and obliterated at the sides, the color and form being also quite similar. The max- illary palpi are rather slender and similar to restrictulus. It is known to me from Canada, westeim Pennsylvania and Colorado. .4KTHRACOPTERYX u. g. Frontal margin not elevated, confluent with the edge of the cly- peus. Antennte a little longer than the head and thorax, joints 3-10 feebly serrate, nearly equal in length, eleventh longer, second shorter, first joint stout, nearly as long as the next two. Maxillary palpi long, the last joint (of both palpi) cultriform, longer than the two preceding joints together. Thoracic margin acute, when seen later- ally nearly straight, terminating opposite the middle of the eye; scutellum oval, slightly transverse. Elytra oblong, humeri obliquely rounded, body apterous. Prosternal lobe rather short, the mouth exposed beneath, the sutures straight, slightly convergent posteriorly, tip of prosternum acute, flexed upward toward the body- Posterior coxal plates abruptly dilated at inner third. Tarsi as long as the tibije, the first four joints decreasing gradually in length and not lobed, claws simple. The above description briefly defines a form which it is by no means easy to place. From the method of classification adopted by Dr. Candeze, which assumes the form of the front as the character of greatest primary moment, the genus should be referred to the division Corymbitites and to the group Dirnites. From Dr. Can- deze I have received the following note: “ For me there remains no doubt, after a mature examination, that it can be placed in the Dimites, where it will form a new genus related to Diadysis (of Australia) and Asorno (of Patagonia) which I will hereafter j)lace in the Diiuites.” NORTH AMERICAN COLEOPTERA. 31 In a sentence immediately preceding he writes: “Its head is the head of a Corymbitite, but the coxte !” Here is the point at issue. The form of the posterior coxal plates, whether abruptly or gradu- ally dilated internally seems to me a character of greater stability, and therefore more reliable as a character than the form of the head. Therefore, I must at this time differ from that learned entomologist, and place it among the Cryptohypnites. In the latter group we find species with the frontal margin scarcely distinct from the clypeal and the labial palpi exhibiting a tendency to elongate, especially in the last joint. From Cryptohypnus the genus may be said to differ by the form of the long maxillary palpi terminated by a cultriform joint. Science owes to Mr. T. D. A. Cockerell the discovery of the spe- cies on which the genus is founded, and both the generic and specific names are due to his suggestion. Had it not been for the necessity of quoting the letter of Dr. Candeze in order to explain why I dif- fered from him, I would have preferred to have elaborated the notes sent me by Mr. Cockerell to publish them under his name. A. liieiiialis n. sp. — Oblong, parallel, moderately convex, piceous, slightly shining, sparsely pubescent; antenme a little longer than the head and thorax, piceous, feebly serrate, joints all longer than wide ; head sparsely punctate, front rather flat, the frontal ridge not continuous across the front; thorax longer than wide, apex feebly emarginate, widest one-third from apex, sides moderately arcuate, slightly convergent posteriorly, feebly sinuate before the hind angles, which are acute, not long nor divergent, distinctly carinate, disc moderately convex, median line feebly impressed posteriorly, without basal incisures, sur- face equally punctate, moderately coarsely, but not closely; elytra not wider than the thorax in front, oblong oval, humeri very oblique, disc striate, strije punctured, intervals flat, irregularly biseriately punctate and somewhat wrinkled, especially at base ; prosternal lobe not prominent, irregularly arcuate in front, the edge not beaded, surface coarsely not closely punctate, apical mucro very oblique, propleurse less coarsely and less closely punctate; metasternum and abdomen still less closely punctate and more shining, the last segment more coarsely and closely ; legs piceous, tarsi usually paler.

XEW SPEEIES AND MISt'EEEANEOES NOTES. BY GEO. H. HORN, M. D. The few new species described below are mostly of curious forms, or of groups not previously represented in our fauna. Others have interest in their relationship with Mexican forms, while several are indicated as inhabitants of our fauna known previously from more tropical regions to the south. A few synonyms have been given which need no special comment. PTEROSTICHUS Bon. P. (Hyperphes) iiiaiiis n. sp. This name is suggested for a species closely ailed to angushis, Imt of rather less parallel form and somewhat larger size, and always of darker color. The head is broader, and more distinctly narrowed behind the eyes, which are larger and more convex. The thorax is more distinctly narrowed behind from being somewhat more arcuate in front. The basal impressions are deeper and longer, while the basal marginal line is very short (in angustus extending across the entire base). The elytra are more depressed, the sides more arcuate. The under side does not present any essential differences. Length 10-12 min.; .-10-.48 inch. In the male the hind trochanter is always two-thirds the length of the femur, and sometimes slightly longer than that, the apex very acute, while in angmtus the same member is rarely more than half the length of the femur and obtuse at tip. The essential differences from angustus are — larger size and less parallel form, prothoracic impressions deeper and longer, basal mar- ginal line here almost absent, except at hind angles, and finally the form of the male hind trochanters. Occurs in Washington, Nevada, and as far south as Placer County, California. P. (Hyperphes) caligaiis n. sp. Very like angustus, but still more slender and elongate. Castane- ous, shining, elytra very finely alutaceous ; head relatively larger, frontal impressions moderately deep, optic prominences normally large, the eyes very small ; thorax longer than wide, narrower at base, sides very feebly arcuate, slightly sinuate in front of the hind angles, which are sharply rectangular, median impression moderately deep, extending to base and nearly to apex, basal impressions sitigle. NORTH AMERICAN COLEOPTERA. 33 moderately deep, arcuate, liasal marginal line entirely absent; elytra oblong, nearly 2mrallel, humeri slightly dentate, surface moderately deeply striate, strije obsoletely punctate, intervals very slightly con- vex ; beneath similar in color, abdomen finely alutaceous, indistinctly punctate at sides in front. Length 10-11 mm. ; .40-.44 inch. In the male the hind trochanter is about half as long as the femur and obtuse at tip. Two sjiecimens have been examined, taken by Mr. L. E. Rick- secker at ISylvania, Cal. This species is evidently closely related to longissimus Bates (Biol. Cent. Am. i, p. 81, pi. iv, fig. 6), although that species is said to have non-dentate humeri. Direct comparison will be necessary to indicate the real differences, as it can hardly be supiiosed that an almost blind species from middle California is identical with one from Guatemala. The two species above described constitute, with migustus, a small group of Pterostichus, characterized especially by a very narrow, almost parallel form. All have small eyes, although they vary in size in the three species. Of the three itianis has the largest eyes, and caligans the smallest. The characters separating them may be tabulated in the following manner : Thorax witli two distinct linear basal impressions, the basal marginal line entire ; hind trochanters of 'J, longer than half the femur and very acute at tip; scutellar stria rarely well marked, often absent inaiiis. Thorax with two basal impressions, the outer quite short, basal marginal line variable, sometimes entire, often visible near the angles only; hind trochan- ters of male half as long as the femur and obtuse at tip; scutellar stria dis- tinct august us. Thorax with but one basal Impression, the basal marginal line entirely wanting; hind trochanters of male as in angustus ; scutellar stria distinct. .caligaiis. The last species resembles in a marked degree, small sj^ecimens of Stenoraorpkus rufipes. I*. Blaiieliardi n. sp.— Form rather robust, piceous, shining, legs and antennfe rufo-testaceous Head smooth, frontal impressions short; thorax cor- date, wider than long, sides strongly arcuate, rather deeply sinuate posteriorly the hind angles rectangular, surface smooth and shining, without punctures at base, median line fine and entire, basal impressions single, deep, straight, ex- tending nearly a third to the front, basal marginal line entire and very distinct ; elytra rather broadly oval, more acute behind, moderately convex, humeri not dentate, striae rather deep, distinctly punctured, the sides of the intervals slightly (5j TRANS. AM. ENT. SOC. XVIII. FEBRUARY, 1891. o4 GEO. H. HORN, M. D. erenate, the intervals slightly convex, a dorsal puncture on the third stria behind the middle; body beneath smooth, shining, prosternuin not margined at tip. Length 6 mm. ; .24 inch. This is the smallest species outside of some in the Cryobius series known to me in our fauna. It has the general aspect of honedus, although less convex, and somewhat more acute posteriorly. It may be known from that species by the following j)oints : Thorax punctate at base, without marginal line, basal impressions arcuate; striae not punctate lioiiestiis. Thorax smooth at base, marginal line entire, basal impressions straight ; striae punctate, intervals erenate ISlaiiicliardi. The unique before me was collected by Mr. F. Blanchard at Highland, North Carolina. BEMBIDIUin Latr. B. haplogonum Chd. is a variety of erosimi Motsch. {mannerheimii Lee.), in which the elytra are pieeous with teneous surface lustre, ti faint paler space near the humerus, and an oblique space near the apex. B. plagiatum Zimm. is a picipes Kby., with a faint pale spot at apical third. B. lacunarius Zimm. is a picipes with imperfectly colored elytra. B. arcuatum Lee. agrees perfectly with specimens of unclulatum St. as sent me from London. B. planum Hald. ; the name is preoccupied, and Guexii has been suggested by Chaudoir, Rev. Mag. Zool. 1868. I>I$Si€ODERUI^ Lee. D. cordicollis n. sp. — Form rather depressed, pieeous to castaneous in color, shining, the darker specimens with a faint feneous lustre, anteunpe and legs always paler. Head smooth, frontal impressions short, in some specimens two punctiform fovese between the eyes; thorax rather more than half wider than long, broadly cordate, sides arcuate and gradually narrowing to the base, the hind angles entirely obliterated, disc feebly convex, smooth, rarely feebly transversely wrinkled, basal impressions short, but rather broad; elytra subde- pressed, oblong oval, strige fine not punctate, intervals slightly convex and smooth , or flatter and feebly alutaceous 9, the usual rows of punctures on the alternate intervals ; body beneath smooth, less shining than above, proster- uum not margined at tip. Length 7.5 — 8.5 mm. ; .30 — .34 inch. In both sexes there is but one anal puncture on each side. The male is more shining than the female, and the elytral intervals more convex. The last ventral of the male is more obtusely arcuate at NORTH AMERICAN COLEOPTERA. 35 apex, that of the female being much more acute and slightly ele- vated in an obtuse carina near the middle. The male has a few squamules on the anterior tarsi. Tibiie straight in both sexes. This species is the most depressed of any in our fauna, and has the thorax much more narrowed behind, resembling a diminutive Polpochile capitata. There is no depression of the lateral margin of the thorax, as is usual in our heretofore described species. Occurs from Fort Yuma eastward to Tucson, Ariz. (Wickham.) I>. crassicollis n. sp. — Form robust, convex, piceous, shining, without trace of metallic surface lustre; antennae, palpi, and usually the labrum, casta- ueous; head impunctate, frontal impressions very short; thorax quadrate, a little wider than long, slightly narrowed at base, widest one-third from apex sides regularly arcuate, margin not depressed, hind angles obtusely rounded, disc convex, median impression faint and short, basal impressions broad, but shallow and vague; surface smooth, with a few longitudinal wrinkles at base; elytra not wider than the thorax, sides feebly arcuate, disc convex, finely striate, stri® not punctate, intervals smooth, very feebly convex, the inner sides of 3-6-8 with the usual punctures fine and rather indistinct; body beneath slightly paler, shining, prosternum not margined at tip, but with two (usually) prominent bris- tles on each side; abdomen very sparsely punctate, coarser punctures on the intercoxal process. Length 12.5 mm. ; .50 inch. Although reasonably certain that both sexes are before me in the live specimens examined, no well marked sexual difierences have been observed. The last ventral segment bears two setie on each side. The middle tibise are not longer than the anterior, are broader toward the tip, slightly arcuate and beset on the outer side with short spinules. The posterior tibise are also very slightly arcuate. The anterior tarsi are not furnished with squamules. This species is evidently very closely allied to acmopoides Bates (Biol. Cent. Am. Col. i, p. 63), which is described as having the elytra cupreous and the sides of the thorax straight and not arcuately narrowing as in the present species. It is the most robust and convex species in our fauna, quite unlike our others, and resembling an Acinopus more nearly than Discoderus. Occurs in southern Arizona. AJV.4TRICHIS Lee. This genus has been divided by Chaudoir (Ann. Fr. 1882, p. 322) into Anatrichis and Oodiellus, the former represented by ouv nihuita, the latter (which Mr. Bates very properly considers a synonym of Oodinm Mots.) typified by mexicanus Chd. (1882) = piceus Mots. (1864). In the paper above cited Chaudoir describes three addi- 3G GEO. H. HORN, M. D. tional species of Anatrichis, two from the East Indies, the third Australian. Four species are referred to Oodiellns, one from Mexico and three from Brazil. Mr. H. W. Bates describes as Anatrichis two more from Mexico which must be referred to Oodiellns, whether regai-ded as a section or a valid genus. The characters of the latter genus are derived entirely from the mouth parts and do not seem to be of sufficient moment for generic separation, as Mr. Bates has remarked, an opinion in which I fully concur. In his posthumous work Chaudoir fails to mention a character of the male of Anatrichis observ'ed by LeConte (Trans. Am. Philos. Soc. 1853, X, p. 391). The middle tibiae have on the inner side at the lower third an emargination resembling somewhat that of the front tibia. This character is not observed in the only male of Oodinus examined. It would be interesting to know what value this has, in addition to those given below, for the separation of Anatrichis and Oodinus. There is, however, one character more easily seen which will sepa- rate the species of the two divisions without, to my mind, having any greater weight than those u.sed by Chaudoir. As far as can be gathered from descriptions the species separate in the following manner: Elytral strife distinctly punctate S. G. Aiiali'icliis. Elytral strife fine and simple S. G. Oodinus. The former is represented in our fauna by A. minuta Dej., with shining, finely punctate surface, the basal impressions of the thorax deep but short. The apex of the prosternum is distinctly margined. The subgenus Oodinus is represented by two species. Form more broadly oval than A. minuta, surface more opaque; first and second elytral striae uniting at base, terminating together in an ocellate fovea ; prosternum not margined at tip l>icea Mots. Form oblong, recalling a diminutive Lachnocrepis parallela, surface shining; strife all partly obliterated at base, an ocellate fovea near the end of the second ; prosternum margined at tip obloiiga n. sp. The genus Anatrichis is properly considered feminine in its termi- nation by LeConte, Chaudoir and the Catalogus. Mr. Bates, how- ever, appears to regard it as masculine from his specific names.

More broadly oval than minuta. The surface is less shining, without punctua- tion and extremely minutely aliuaceous ; the median line of the thorax is ex- NORTH AMERICAN COLEOPTERA. 87 treniely fine and the basal impressions very shallow and vague; the elytral stria- are fine and sliarp, without punctures, the intervals flat, minutely alutaceous, the third with the tvvo dorsal punctures behind the middle; the prosternum is obtuse at tip and without marginal line. Length 6 mm. ; .24 inch. The specimen before me is a male. The first four joints of the anterior tarsi are dilated as in viinuta, but the middle tibiae are simple. Occurs in our fauna in southern Texas and Central America to Santarem, in Brazil. A. obloiiga n. sp. — Oblong, piceous-hlack, somewhat shining; antennse pi- ceous, the three basal joints and palpi rufo-testaceous ; head without frontal im- pressions, the surface extremely minutely alutaceous: thorax about one-third wider at base than long, sides arcuately narrowing to apex, median line very finely impressed, the basal impressions deep but short, surface minutel.v aluta- ceous; elytra oblong, sides feebly arcuate, strife sharply impressed but not punc- tate, not quite reaching the base, an ocellate fovea near the base of the second, intervals flat, verv minutely, sparsely punctate and finely alutaceous, the dorsal punctures of the third interval indistinct; body beneath more shining than above, the prosternum with marginal line at tip ; legs castaneous. Length 6 mm. ; .24 inch. This species is evidently closely related to lougula Bates, and may even be the same, although I can hardly apply his description of the thorax to my specimen : “ transversim quadrate, antice paullo magis quam postice angustato.” The surface sculpture is so minute that a moderately high power is required to detect the alutaceous structure and the elytral punctures. One specimen 9 » Texas near the lower Rio Grande. OODEN Bon. From the description given by Chaudoir, in 1882, it seems that the species known to us as texaims Lee. is the same as mexicanus Chev. 0. duodecimstriafm Chev. According to Chaudoir, who has ex- amined types, this name should replace 0. Lecontei did. in our lists. STEXOC'REPIS Chd. A specimen in my cabinet collected near the lower Rio Grande of Texas seems to be referable to S. chalcas Bates {chalcoclirous Chd.), Biol. Cent. Am. Col. i, )i. 47. It is nearly as elongate as Lachno- crepis, but with a form of thorax as in our Oodes s.s. The striie are very distinctly punctate and the sides of the intervals crenate. The under side of the body is iridescent, the sides of the metaster- num with coarse punctures, the first two ventral segments at the sides with very coarse punctures. Prosternum not margined at tip. On the elytra the seventh stria is replaced by a row of extremely indistinct fine punctures. 88 (iEO. H. HORN, M. D. If the insect before me really represents S. chalcas, and of this I have very little doubt, the genus seems to me intermediate between (dodes s.s. and Lachnocrepis. With the former it agrees in having the first foxir joints of the anterior tarsi of the male dilated and papillose beneath, although the posterior tarsi are not pubescent be- neath. The mode of dilatation of the tarsi is the same as in Lach- )iocre])is. It seems to me that Chaudoir was not true to his own methods in uniting Stenocrepis, Stenous and Crossocrepis as sections under the first name. If it be advisable to se[)arate any of them from Oodes, it seems to me desirable to retain Stenocrepis apart, while the other two could be very well united. In Oodes s.s. the entire under side of the body is comparatively smooth, in the others above mentioned the sides of the metasternum and the metapleurse, and usually the sides of the first two ventral segments are very coarsely punctate. EUPHORTIC’US Horn. E. occitleiitalis u. sp. This name is proposed for a species occurring near Los Angeles, Cal., resembling jm/6escens Dej., and differing in the following manner: Surface more brilliantly aeneous. Elytral striae very faint, the punctures fine, ronucl and rather distant, intervals flat, punctulate. Length 4 mni. ; .16 inch. The punctures of the elytral stripe do not extend beyond the mid- dle in either species, but in puhescens they are large and more closely placed than their own diameters. On the other hand the fine punc- tures of the intervals are sparser and less distinct in occidentalis than \\\ puhescens. In the latter species the tibipe are always jialer than the feuKji-a, in the former they are as dark as the femora. PCECIEOEHRUK Bouv. To this genus should be referred the species described by me as Htethon errans. Poecilochrus may be distinguished from Stethon by the straight prosternal sutures. In both genera the metasternum has a short groove limited by an elevated line begining at the inner side of the middle coxae and directed backward in a straight line. Dronueolus pnsillus Horn. — This species, while very unlike our others, has a number of related forms in the Mexican fauna. They nearly all have the |)rosternal sutures very finely grooved and the NORTH AMKRICAN C0LE0PTJ:RA. 39 propleural triangle is in absolute union with the prosternuin, or very nearly so. In facies they more nearly resemble Thambus than Dromseolus. I have already called attention to the fact that in Microrhagus (Trans. Am. Ent. 8oc. 1886, p. 35) the pubescent fovea on the last or penultimate segment was a sexual character. While the fact is correct, I have wrongly attributed the possession of it to the male. Since then the same character has been elsewhere observed, Enio- mophthalrnus americanus, where the female has the fovea and the male a small tubercle. In the table of Microrhagus (Mon. des Eucnemides) under “23,” p. 528, two series of species are separated, the one with femora scarcely darkened, the other with them decidedly brown or nearly black. Fortunately but three species are sepai’ated under the last EKA Lee. T. erosa Lee. The usual form of this species as found at San Diego and vicinity, has the reticulations of the elytra very coarse. The color is })ale orange-yellow, always with the tip {)iceous for a short distance. The specimens seem about equally divided between those with a piceous band across the middle and those without it. There occurs in Owen’s Valley, where I collected it rather abun- dantlv, a form which seems almost entitled to rank as a distinct species, although I consider it merely a race. T. erosa, race hitecincta. Elytra with reticulations much closer than in the typical form, piceous space at apex better indicated, at middle a rather wide, ex- actly transverse i)iceous fascia, the edges undulating. This form seems a little more robust, and the texture of the elytra firmer and less coriaceous. I»YROT.\ Lee. |». AkliHi*»«tiaiia n. sp. — Elongate, black, surface shining, the front, a tri- angular space at apex of thorax, the base and entire limb of the elytra narrowly red ; antennte black ; head sparsely punctate, a vague lontritudinal impression of the front; thorax narrow, sides parallel near base, narrowed at apical third, a vague depression at middle of base, surface shining, sparsely punctate; elytra vaguely bicostate, the surface nearly smooth, the punctures minute and very indistinct; body beneath black, shining, very sparsely punctate; legs black. Length 15 — 22 mm.; .60 — .80 inch. PI. 1, fig. 9.

This species is related to dnbiiabilis (yittigera || Lee.), but differs notably in the smoother and more shining stirftice, the costte of the elytra are less distinct and finely, the color of the thorax and legs is different. Occurs in N. IMexico f Akhurst ) and at Tucson, Ariz. (Wickham). NOFiTH AMERICAN COLEOPTERA. 45 i»YROC'IIKOA Geoff.

Length 13 mm. ; .52 inch. Very distinct from any of our species by the entirely black color, the thorax and scutelluin alone orange-yellow. One specimen 9 > collected by Mr. D. W. Coqnillett near Los Angeles, Cal. BUPRESTID.E. Pcecilonota debilis Lee. An examination of the type of this insect shows it to be merely a female, rather poorly developed of F. cyanipes. In the female of the latter when of full development there is a feeble emargination of the last ventral segment. In the debilis the segment is nearly entire. DYSTAXIA Lee. The males of D. Murrayi Lee., the only species known, have the last ventral deeply and acutely triangularly emarginate. The an- teniue are slender and extend to a point opposite the first ventral suture, the female has the last ventral segment broadly rounded and entire, the antenme shorter, not i-eaching beyond the end of the metasternum. In mature specimens the body above is of an entirely uniform malachite green, with but feeble trace of pubescence. Before attaining maturity the specimens are dark bronze, with a coppery tinge, and the gray pubescence is more consi)icuous. On a specimen of this kind is founded D. Lecontei Thoms. SCHIZOPITS Lee. In the typical species of this genus, S. Icefus Lee., the sexes differ in a more striking manner. In the male the under side of the body, head and thorax, all the femora and the first two joints of the an- tennie are bluish submetallic. The elytra are orange-red, with a narrow sutural edge blue. Probably when quite recent the elytra are brighter red. The tibise, tarsi and anteniUB, are I'ufo-testaceous. 46 GEO. H. HORN, M. D. The last ventral segment is broadly triangularly eniarginate. The antennje do not extend much beyond the hind angles of the thorax, and are similar in the sexes. The female is entirely of a uniform blue above and beneath, some- times quite green, the last ventral entire. For the opportunity of recording the sexual differences I am in- debted to the National Museum at Washington, where numerous specimens were received from San Diego, Cal. tS. Sallei Horn was described from a female with scarcely any trace of metallic siuTace color. The elytra are similar in color to Mas % , except that there is a darker oblique vitta extending from the humeral umbone nearly to the sutural angle. The head and thorax are darker in color. The oblique impression of the thorax, on which I laid some stress, seems not to have great value, as it seems to be a variable quantity in ketm. The claws of Sallei are, however, much less distinctly cleft, and seem rather to be provided with a small tooth at middle after the style of some Lachnostern^e. This species was collected at Mariposa, Cal., by Mr. Alphonse Thevenet. Mr. F. Blanchard is quite correct in recording the presence of the “ ante-coxal piece” of the metasternum in both Schizopus and Dys- taxia. The presence of this piece seems to be quite characteristic of the Buprestidse. In the genus Lissomus, of the Throscidse, there is no trace of this piece, so that by the fortunate discovery by Mr. Blanchard we have a more ready method of separating the latter family from the Buprestidte than previously existed, Lissomus having always been an annoying element. While the presence of the “ ante-coxal piece” and its modification, or entire absence, plays an important part in the Adephagous series, it would hardly have been suspected to have similar utility in a series so remotely separated as the Serricornia. ACTENODES Lac. A. ineiKlax n. sp. — Form of calcarata, but somewhat more convex, color dark greenish bronze varying to cupreous, feebly shining; antennae short, ob- tusely serrate ; front rather flat, coarsely and closely punctate, not longitudinally impressed, surface rather uneven in the female; thorax more than twice as wide as long, sides parallel, with a slight siuuation, obliquely narrowed at anterior third, disc regularly convex, moderately coarsely and closely punctate, with a NORTH AMERICAN COLEOPTERA. 47 tendency to form transverse strigae ; elytra with rarely a trace of a costa near the suture, the surface scabrous, with a tendency to form transverse strigae to a slight extent, the oblique portion of the margin serrate; body beneath more shining than above, punctate and transversely strigose. prosternum more coarsely punctate; anterior femora toothed at outer third. Length 12 — 17 mm. ; .48 — .68 inch. In both sexes the last ventral is truncate, squarely in the 9 > slightly eniarginate S . The anterior tibite are serrate in the male very distinctly, but in the female this is but faintly indicated. This insect has been a long time in my cabinet, but I refrained from naming it, hoj)ing that it was a known Mexican form, or that it would be described in the “ Biologia.” This not proving the case, and as specimens are occasionally being sent me I have thought it well that it should be described. Known to me from Texas to Fort Yuma. A specimen before me is labeled Illinois, but the locality is open to doubt. Bibliographical Reviews. In a recently published part of the “ Biologia Centrali-Americana (vol. iii, pt. 1),” in reviewing the Throscidje, it was observed that Throscus, as then constituted, was clearly divisible into two genera ; Throscus includes those in which the metasternum is simply ob- liquely impressed, while Aulonothroscus will receive those with a rather deep and well- defined groove. To this division belong validus, punctatus, invisus, condridor, convergens and pugnax, the remaining species will continue as Throscus, all the European species belonging here, and must be accepted as the typical forms. In the same essay, a few pages after, it will be observed that the name Tharops has been superceded by Isorhipis, the former name having been previously used. As an illustration of the rather restricted distribution of the Euc- nemidae generally, it will be observed that but few species occur south of our boundary which are found within it, these are Nematodes atropos, Mirn'orhagus humeralis and Anelastes Druryi, the first being somewhat doubtful, while the last is represented in both its races the shining {Latreillei) and opaque (Druryi) as far south as Guatemala. 48 (ii:0. H. HORN, M. D. In the Mexican fauna the species of the family Throscidje show nothing in common. In onr fauna Throscus sens. lat. is represented hy thirteen species, and in ^Mexico by five, while Drapetes contains twenty-six in ^Mexico and hut four with us, in addition to which Lissomus has twelve Mexican species, and is totally unknown in our fauna. Pactopus makes a closer approach to the Eucnemidse without having any parallel in Mexico. o There has recently a])peared from the able hands of Dr. Candeze a work entitled, “ Catalogue Methodique des tllaterides connus en 1890,” which will have great value to those interested in the study of that family. In it all impertinent synonymy has been omitted, only such being given as has not already obtained sufficiently wide circulation. But little has been observed worthy of correction in reference to our species, except that Megapenthes granulosus Mels, is on ]). 98, while its male is found on p. 190 as Ludius limbalis Hbst. Our Betarmon higeminatus Rand, has been omitted.

ANDRENA. In the study of the mutual relations of flowers and insects I have found many insects which I could neither determine myself nor get determined by others. Conspicuous among these are the species of Andrena. In order, therefore, to get names for use in my biological work, I have undertaken to describe as best I could the species which occur in my neighborhood. Some of them may have been described before, by Smith, in British Museum Cat. Hym. and in New Spec. Hym. Brit. Mus. After careful study I have been unable to deter- mine more than two of Smith’s species. The fact that a specimen agrees in every detail with Smith’s description would not, to my mind, establish the probability of its being the same as its type. His descriptions are limited almost entirely to the colors of the pubes- cence, which is variable and liable to fade. Thus, of the twenty-four female specimens of A. Cressonii, only three show the normal color of the pubescence. The color of the surface is also very variable. The abdomen sometimes varies from entirely red to entirelv black. Sets of specimens in which the legs are commonly black, with the apical joints ferruginous, often show individuals having the tarsi, the middle tibiae at tips, and the hind tibiae entirely ferruginous. In all, or most of the species, the ground surface is minutely rough- ened. Unless there is a distinct punctuation in addition to this, I call the surface impunctate. One trouble with Smith’s descriptions is that one cannot always be certain whether he refers to this minutely roughened surface or to a distinct punctuation. Of the twenty-six species of Andrena mentioned in this paper, I have both sexes, except in five cases. I have taken the sexes of eleven species in copula. These bees can best be collected by watch- ing flowers of willows in Spring and of Composite in fall. The females should be identified first and the males referred to them. I submit a synopsis of all the species which occur in my neighbor- hood (Carlinville, 111.) with notes on their time of flight and the flowers which they visit, as well as descriptions of the new species. Besides those given below I have ten sets of specimens which indi- cate the presence of several additional species. TKANS. AM. ENT. SOC. XVIII. (7) .\PKIL, 1891. 50 CHARLES ROBERTSON.

I have two specimens of S. mandihularis Cress, whose wings show only two submarginal cells. In one the first transverse cubital is represented by stumps, while the other specimen shows no trace of it.

SOUTH AMERICAN DIPTERA. 67 CATAI.OGIIE OF THE HE^CRIBED SPEC’IES OF SOUTH AMERICAN ASIEID.E. BY S. W. WILLISTON. 'File following preliminary catalogue of the described species of South American Asilidse is offered in the hope that it may lighten the labors of students of the South American Dipterous fauna. It was originally prejiared, two years ago, as a preliminary to the study of a Brazilian collection in this family, and has been recently sub- jected to a careful revision. It will be strange if, among so many references, some errors, both of omission and commission, are not found. I can only say in extenuation of such, that the entire paper has been repeatedly written and the references as often compared. Schiller’s list of specific names of the Asilidie of the world, which seems to be very complete to 1860, has been of material service, as also Lynch’s partial catalogue. The distribution of the genera is chiefly that of Schiner ; some few changes have been made in ac- cordance with Lynch’s, Osteu Sackeu’s, or my own views. A very few of the less important works have been inaccessible to me, and it is in them that additional references may be found. The references thus taken at second hand will be found preceded by an asterisk. No references later than 1889 are included. I.— DASYPOGONIN.B. DASYPOGON. Sensu, latissimo. aberrans Wiedemann, Dipt.

Soft liodied insects of the smallest size. The females and the young larvse, of both sexes, are degraded, mite-like in appearance, oval or elli))tical in shape, with the head not distinctly sej)arable from the thoracic segment, apjiearing merely as a segment with rounded eyes placed toward the sides, the short, subsetaceous, 5- to 11-jointed antenme being situated just a little in advance. Ocelli usually present. Beak usually 1 -jointed, and seldom with more than 2 joints, enclosing 4 long, delicate setae. Legs usually short ; tarsi 1 -jointed and usually with digitules. The adult males, in this anom- alous family, present a very different appearance from the females and young larvie ; they are elongate ovate, with a well developed thorax, a large scutellum, a distinct, small, rounded or quadrately shaped head, with the eyes quite large, either smooth or facetted, while the antenme are long, filiform, and composed of from 9 to 11 joints, usually ])ubescent, but occasionally with whorls of hairs. The beak, in this sex, is wanting ; where it should be, are two large, shining ocelli. The legs are of moderate length, never greatly thick- ened ; the tibiae sometimes as thick, or thicker than the femora; tarsi 1 -jointed, stout, ending in a single claw, and usually furnished with knobbed digitules. Most of the males known in this family have two wings, the venation consisting of a single longitudinal vein with a simple, oblique, discoidal branch, the hind wings being aborted, and in their place is a pair of halters, as in the Diptera. Some few males in the genus Lecaniwn have been discovered recently to be entirely wingless, and it is quite probable that with closer study wing- less males in other genera will be found. Subapterous males are not uncommon. The abdomen in the male is simple, or terminates in two long caudal setse, a brush of filamentous down, or then armed with a long stylus, with oi‘ without caudal setse. The habits of this anomalous family are quite interesting; the vast majority of the species becoming quiescent and stationary upon their food-plants, cover themselves with a waxy or calcareous sub- stance, which, together with their castings or moults, affords a jiro- tection for their soft bodies, termed a scale, shield, test, sac or en- venope. The name, therefore, popularly given to them — “Scale insect” — is very appropriate, although some of them do not become GENERA OF COCCID^. 93 quiescent and form the scaly covering, but are capable of moving freely about on their food-j)lant, entirely unprotected, oi- then only covered with a filamentous, floccnlent or pulverulent substance, whilst a few species have been discovered in Australia living in galls or excrescences, on the leaves of the Eucalyptus tree. I also know of a gall-rnaking species in Florida. ihe family may be divided conveniently into five subfamilies, apparently natural groups, based upon the studies of Signoret, Tar- gione, Low, Masked, Comstock, Atkinson and others, recognizable by the aid of the following table ; Table of Subfamilies.

NORTH AMERICAN LEPIDOPTERA. 103 KOTES OX SOME X0CTEI03E, WITH DESCRIPTIOXS OF XEW^ OEXERA AXD SPECIES. BY JOHN B. SMITH. Cernia olivacea n. sp. — Ground color an olivaceous gray, with bluish green and white powderings. Head and thorax irregularly mottled, with a con- siderable admixture of black scales. Basal line distinct, black, followed by a white line. T. a. line black, preceded by a white line with long outward teeth on the subcostal and median veins, an incurve in submedian interspace, with another long tooth on the internal vein. T. p. line is irregular, rivulous, in gen- eral course a rather even outcurve. S. t. line indefinite, the space between t. p. line and outer margin being irregularly blotchy; an even dusky terminal line. Fringes pale, cut with fuscous. Claviform concolorous, defined by a black semi- circle below the orbicular and a vague black pow’dering from the horns of this to the t. a. line. Orbicular moderate in size, round, concolorous, defined by a greenish annulus edged with black scales, and with a whitish central dot. Reni- form large, somewhat constricted medially very incompletely defined in black, with greenish powderings which extend to the costal margin. Secondaries smoky fuscous, somewhat paler basally, with a small discal lunule and a faint extra median line. Beneath, primaries blackish powdery, paler along inner margin ; secondaries whitish, with a dark discal lunule and a powdery outer margin. Expands 1.20 — 1.28 inches; 30 — 32 mm. Hab. — Colorado ; Sierra Nevada, Cal. I have seen three specimens of this very distinct species, all males. Two are from Mr. Edwards, one of them rather rubbed, the third is from ]\Ir. Bruce’s collecting, sent several years ago to Mr. Cramer, now in collection United States National Museum. In this specimen the green has faded to the sordid yellow so commonly assumed by this color in the noctuids, but in maculation there is absolutely no difference. It is much larger than the eastern C- cora, and the de- tails of maculation differ quite widely while the pattern remains similar. It is fully congeneric with our eastern species, without meaning to assert its distinctness from Bryophila. ’ I Pacliiiobia ciiieraseens ii. sp. — Pale luteous gray ; sometimes with a slight reddish suffusion, sometimes quite well powdered with black scales. Head and thorax concolorous. Basal line distinct, rigid, single. T. a. line single, blackish, oblique, outwardly angulated below the costa, nearly straight through the cell, outcurved in the submedian and marginal interspace. T. p. line single, blackish, distinct, only a little outcurved over the cell, finely crenulated. S. t. line concolorous, marked by a defined blackish preceding shade, which fades into the ground color before the t. p. line. A broken brown terminal line, followed by a faint yellowish line at base of fringes. Claviform wanting; orbicular round 104 JOHN B. SMITH. or oval, hlackisb. without defining line. Ecniforin large, upright, ohlong, hlackish, without distinct defining line. Secondaries smoky gray, uniform, with a fairly distinct yellowish line at base of fringes. Beneatli gray, primaries vaiying to smoky brown, secondaries ))owdery. A common, varialily complete outer line and a distinct large discal spot sometimes obscured on the primaries. E.xpands 1.20 — 1.40 inch. ; 30 — 3.5 mm. Hub. — Alameda County, Cal., September and October. Four male specimens are in the museum collection (through C. V. Uiley) hearing the red number 339. This species is aberrant in color for the genus, hut in wing form and in pattern of ornamentation it is allied to carnea. Its luteous gray color, single median lines, and contrasting black ordinary spots, render it easily recognizable. The antennae are “ brush like,’’ l.e., the joints slightly produced laterally and furnished with bristly tufts. The thoracic vestiture forms an indefinite dorsal crest. The male genitalia have the harpes ohliijue at tip, forming a little pro- jecting tooth interiorly. The clasper is a single, stout, straight, pointed, corneous spur. " A / ^ l*acliiiobisi elevata u. sp. — Ground color of the reddish gray usual in this genus. Head and thorax immaculate. Primaries with the ordinary lines single. Basal line interrupted, rather indefinite. T. a. line incomplete, ap- jiarently upright and rather even to internal vein, below which it makes an outcurve. T. p. line complete, even, exserted over the cell, and somewhat ir- regularly ohliipie below to margin. A paler, more grayish shade through the s. t. space, in which a series of interspaceal brown dashes indicate the s. t. line. .\u interrupted terminal line. Claviform a yellowish streak from base to near middle of median space, outlined beyond t. a. line by a narrow black line. Or- bicular elongate, the angles drawn out toward base and apex. Eeiiiform small, lunate. Both spots are a somewhat paler gray and outlined by black scales. Secondaries whitish, smoky toward apices. Beneath whitish, powdery, with a diffuse common outer line and a moderate discal spot on all wings. Expands 1.40 inches; .35 mm. Hab. — Colorado (Bruce). A single good male from Mr. Neumoegen’s collection. The speci- men has the antenine serrate and bristled, and is therefore allied to C'lrnea, than which it has .somewhat more pointed wings and entirely diflerent markings. The cell is not black-filled around the ordinary spots, and the character of the transverse lines is entirely different. The genitalia consist of a broad harpe with obtusely rounded tip, inwardly fringed with spinules. From the centre of this arises a broad, excavated, corneous process, with an irregular outline, form- ing the clasper. NORTH AMERICAN LEl’IDOPTERA. 105 Ciii'iiesMleM f'lii^iiiiaciila n. sp. — Head and thorax mouse-gray, collar with a blackish central line. Primaries dull red-brown, subcostal and median vein white i)owdered. Basal line geminate, well defined, included space with white powderings. T. a. line geminate, interrupted below costa, a long inward angle on cell, then evenly oblique outwardly to hind margin. Below the median vein the defining lines are well written, the included space concolorous. T. p. line even, outcurved over cell, thence parallel with outer margin. The inner de- fining line is a series of blackish lunules, the outer a vague, diffn.se line, the in- cluded space very slightly paler than ground color. S. t. line marked only by the slight difference in shade between s. t. and terminal spaces; an interrupted, sublimate terminal black line, followed by a narrow yellow line at base of fringes. Apical spot powdered by a few white scales; a black basal dash below median vein, joining to the moderate, black margined claviform. A black filling to the cell before orbicular, and between the ordinary spots. The latter are fused, the orbicular oblong, oblique, merging interiorly into the reniform, which is some- what extended outwardly from its lower angle. The combined spot narrowly black ringed with a white interior line and a few white scales relieving the other- wise concolorous spots. Secondaries even, smoky fuscous, with paler, interlined fringes. Beneath smoky fuscous, powdery, with an incomplete outer line and somewhat indefinite discal lunule. Expands 1.28 inches; 32 mm. Hab. — California. A single male specimen iti good condition. The characters of the tessellata group are well marked, and the sjtecies is intertuediate between divergens and redhnicula, differing amply from both in the fused ordinary spots. The white marked veins are like divergens, while the s. t. line is like redimieula. The male characters agree with those of the allied species, and figure 64 of my Revision of Agrotis will answer for this species equally well. I*erig<*a piilveriileiita n. sp.— fTi-ound color a vague, powdery reddish gray, varying in tint according to the relative ju-edominence of red, white, or blackish scales. All the noiinal maculation present, hut obscured by the pow- dery ba.se. Basal line geminate, concolorous, defining lines fuscous or blackish, twice augulated. T. a. line somewhat paler, with fuscous or black defining lines, not always complete and sometimes vague; outwardly oblique, somewhat curved, inwardly angulate on the median and submedian veins. T. p. line ob- soletely geminate, the inner line lunulate, the outer vague and even, sometimes wanting, its course evenly bisinuate without the usual long outcurve from the costa over reniform. S. t. space palei- than median and usually also than terminal space; s. t. line pale, diffuse, sinuate, marked by the difierence in shade between s. t. and terminal space, and also djy a more or less obvious preceding shade, h'ringes interlined with fuscou.s, feebly scalloped: median space, as a whole, somewhat darker than the rest of the wing; a dusky or blackish median shade which in the submedian interspace sometimes forms a complete connection be- tween the median lines. Claviform small, though quite wide, concolorous, in- completely outlined in black. Orbicular round or oval, oblique, pale ringed with dusky centre. Reniform uiiright, quite large, somewhat constricted centrally, pale ringed with concolorous or paler center. A dusky costal iritch in the s. t. TRANS. AM. ENT. SOC. XVIII. (14) MAY, 1891. 106 JOHN B. SMITH. space and a paler apical patch in terminal space. Secondaries fuscous, with a broad black outer margin, a narrow preceding dusky line and a dusky discal lunule. Fringes pale, interlined with fuscous. Beneath powdery, primaries darker, both wings with a discal spot, narrow outer line and broad dark outer margin, all variable in distinctness. Expands 1.00--1.08 inches; 25 — 27 mm. Hub. — Colorado (Bruce); Las Vegas, N. Mex. (Meeske); New Mexico (Show); Arizona (Edwards). This little species has long puzzled me, and I refer it to Perirjea, rather because it is congeneric with P. pei'plexa Grt., than because it strictly belongs here. Four of the specimens collected by Mr. Bruce are in the collection of the United States National IMuseum, two of them labeled simply “ Colorado,” the others labeled “ Foot-hills.” There is little or no variation, and the species once generically [ilaced, is easily recogniz- able. l*oliit pul VPrnloiita n. sp — Ground color a powdery ashen gray, the markings indefinite, vague. Basal Hue black, interrupted, apparently single. T. a. line single, black, rather diffuse, outwardly oblique and somewhat outcurved between the veins. T. p. line crenulate. outcurved over the cell and parallel with outer margin below that point, blackish, interrupted, almost lunulated, and nearly obsolete toward costa. This line is quite well removed toward margin, widening the median space and narrowing the space beyond to the outer margin. A series of somewhat diffuse iuterspaceal black marks indicates the s. t. line: a series of small terminal lunules. Fringes gray. Claviform vaguely indicated by a blackish shade. Ordinary spots vague, indefinite, concolorous, incompletely outlined, apparently of the usual shape and proportionate in size. An oblique, diffuse blackish shade from costa, outwardly over the reniform and darkening it interiorly; continued as a vague fuscous shading through the median space. Secondaries dirty white, powdery, veins soiled, a dusky lunate marginal line and discal spot and extra discal line of under side showing through. Beneath whitish, powdery, with a common extra discal line and a discal spot on all wings. The hind angle of primaries is somewhat retracted ; thorax with a small, divided anterior crest, and a more distinct posterior tuft ; abdominal tufts small. Ex- pands 1.88 — 2.08 inches; 47 — 52 mm. Hab. — Colorado. Two male specimens with serrate and tufted (brush-like) tintenna. This species, though referred to Polia, jirobably cannot remain in this genus. It is referred there because it is quite close to and per- fectly congeneric with Polia contacta Wlk., which it resembles both in size, color and general habitus, differing abundantly in many re- spects. The species liears a very decided resemblance to Mamestra discalis, and a specimen in the Museum collection (from the Meske collection) bears Mr. Grote’s label, Mamestra discalis. The specimen NORTH AMERICAN LEPIDOPTERA. 107 was collected by Snow, and I feel assured there are others of this species so misnamed. The other specimen was sent me by Mr. Bruce. The genus Folia contains quite diverse material, and the species will probably be distributed among other genera, some mayhap to Hadena. Indeed, Mr. Grote has described the same species as a Hadenu (diversilineata), and again as a Folia (illepida). €AL,OPHASIA Steph. Head not retracted. Thorax with fine, smooth vestiture. Abdo- men without dorsal tufts. Antenme of male with short, rather dense cilire, at base with a feeble tuft, thorax posteriorly with a truncate tuft. Primaries short, widening outwardly, more strongly rounded at internal angle, outer margin and fringes entire. The above char- acterization is from von Heinemann (Schmett. Deutsch. 391), and with it agrees fairly well a species which does not seem to fall in naturally with any American genus known to me. In wing form the species agrees well with opalina ; in type of maculation it is more like platyptera, the latter being wider Avinged than its congener. PalopliHSia strigata n. sp. — Head, thorax and primaries ash-gray. Head marked with fuscous, collar paler at base. Thorax with an admixture of fus- cous scales. Primaries with a dusky shade through the cell and terminally, the transverse lines obsolete; the veins are ail black marked, and the wing has therefore, a strigate appearance. Claviform long, extending from the base to beyond the middle of the wing, with narrow black defining lines, filled with a reddish sulfusion. A faint reddish tinge beyond the reniform, which is white ringed, narrow, upright, with an inferior spur projecting inwardly toward the orbicular. The latter is narrow, clavate, oblique, white ringed. On veins 3 and 4 the dusky terminal shade is cut by a white shade accompan.ying the veins- a row of small, dusky terminal lunules. Fringes cut with fuscous, and rather lout^ Secondaries whitish basally, soiled fuscous outwardly, the veins dusky. Beueatl: whitish, pow’dery.. Expands 1.20 inches ; 30 mm. Flab. — Colorado (Bruce). Two female specimens are before me, neither of them entirely perfect, but yet in excellent condition. The species has the appear- ance of Oncocnemis without its structure. One of the sjiecimens is in the United States National Museum. I>KY0I50TA Lederer. Eyes lashed. Tongue strong. Thorax arched, with distinct an- terior lateral angles. Anterior femora not dilated, tibicT unarmed. Of median size, head and thorax with short, coarse vestiture, the hit- 10(S JOHX B. SMITH. ter mostly flattened scales, collar not crested. The palpi with coarse vestiture and small terminal joint. Antenme at base with a tiift of hair, serrated in the males, with bristle tuftings. The thorax quad- rate, laterally produced at the angles, with smooth anterior and pos- terior tufts, abdomen untufted. Primaries short, not greatly widen- ing, apices not acute, margin evenly rounded, fringes scalloped. This is von Heinemann’s definition, and it agrees well with the European species, but not at all with the American species referred to the genus. Dryobata opina Mr. Grote now refers to Valeri)i, while stiymaia is utterly unlike the European species. The wing form is alisolutely different, the fringes are only feebly sinuate and not scal- loped, and the abdomen is prominently tufted ; but I know at jiresent no other genus to which stigmata could be better referred, and as I believe it has congeners in other genera I will simply call atten- tion to the fact, here, preliminary to the description of three species agreeing better with the description of the genus, but very unlike stigmata in every respect, and, though themselves congeneric, and with the same habitus, differing quite strongly in antennal structure. The species are ash-gray, with a reddish or brownish suffusion, ])owdery, all the maculation well marked. The ordinary spots are well sized, and as a whole the species have a very decided resem- blance to Litholomia napee in type of maculation, emphasized by the more or less prominent, rigid, dark, median shade or line, which forms the most obvious ornamental feature. One of the species which I had dubbed Hadena latifascia, perhaps in one or two collec- tions, I find is Prof. French’s Homohadena elda. It has nothing, whatever, in common with Homohadena, and this species is perhaps nearest of all to tyjiical form of the genus. I>i\yobata elda French. 1887 Can. Ent. xix, 5, Homohndena. The male autennge are di.stiuctly and well pectinated; in the female the joints are marked. A broad brown shade with blackish defining lines fills the space between the ordinary spots, and below the median vein its outer border extends along the t. p. line. Four specimens in the National Museum collection (through C. V. Riley) are from Nevada County, Cal., Septemher, collected by Koebele, and Mr. Edwards has also sent it to me labeled Sierra Nevada, Cal. I>ryobata rectiTai^icia u. sp. — Eather dark bluish ashen. Collar with a broad median black line. Basal half line distinct, pale, obsoletely geminate; a short, black, longitudinal basal line extending to the half line, the inclosed costal NORTH AMERICAN LEPIDOPTERA. 109 space paler and with a brick-red tinge. T. a. line upright, or a little outwardly oblique, geminate, outer defining line usually very distinct and touching the orbicular in its course. T. p. line geminate, inner line darker, included space paler; in course it is very even, widely outcurved over the reniform, altogether what might be termed S-shaped, with most of lower extension lopped ofl’. The s. t. si)ace is pale, except costally, darkening to form a continuous dusky shade before tbe s. t. line, which is pale and irregularly sinuate. Tliere is an admix- ture of reddish scales in this preceding shade which is most obvious at anal angle. A prominent, rigid black line from the costa, forming the inner margin of reniform and continued thence to the hind margin at t. p. line. Claviform small, indefinite, marked only by a vague brick-red shade. Reniform large, kidney-shaped, suffused with brick-red : a black line at base of fringes, which have a dusky interline. Secondaries soiled white, veins and terminal line dusky. Beneath whitish powdery, with a more or less complete outei' line and discal spot. Expands 1.24 — 1.40 inches; 31 — 3.5 mm. Hab. — Sierra Nevada, Cal. (Edwards). The anteimte of the male have the joints but feebly marked and ciliated, not at all serrate, much less pectinated. The transverse median line corresponds to the outer defining line of the median shade in elda, but is more prominent. The differences in details need not be pointed out where structural characters declare the species difierent. An incomplete specimen is in the United States National Museum ; the wings and antennm are, however, perfect, and the specimen is one of my types. Dryobota. ciirvitascia n. sp. — Asheu-gray or darker, with or without an admixture of hiick-red scales, the black maculatiou consisting generally of elevated scales, giving the species a rough or “squammose” appearance. Collar inferiorly pale, a vague reddish median line, surmounted by an equally vague blackish one. Primaries, basal line geminate, blackish, vague, reaching to the short black basal dash, along which a brick-red shade is more or less marked. T. a. Hue geminate, incomplete, outwardly oblique and slightly curved between the veins. T. p. line vague, scarcely definable, obsoletely geminate, evenly out- curved over cell, and incurved beneath. The s. t. space is outwardly a little paler, a partial series of black or blackish lunules, becoming more distinct toward inner margin ; an admixture of reddish in these lunules also increases toward anal angle. Terminal space dusky; a blackish terminal line and a narrow pale line at base of fringes. Claviform apparently obsolete. Orbicular oblong, ob- lique, concolorous, with a narrow black margin and a very narrow white annulus. Reniform narrow, quite long, lunate, shot with reddish, defined by black and white scales rather than lines. A dusky median shade, feebly Insinuate, touch- ing neither of the spots and reaching margin between the ordinary lines. Sec- ondaries soiled white or smoky, with a blackish terminal line. Beneath pow- dery, pale, with a variably distinct discal spot and outer line. Expands 1.12 — 1.20 inches ; 28—30 mm. Hab. — Sierra Nevada, Cal. (Edwards), September ; Placer County, C'al., through C. V. Riley. 110 JOHN B. SMITH. The Placer County specimen in the United States National Mu- seum is the smallest of the three, and is also most obscurely marked. It lacks the brick-red shades altogether, the gray is more sordid and even, and the maculation is less definite than in the other specimens. The male antemue are rather lengthily serrated, almost pectinated, differing from both the j)receding species in this character as well as in the median shade, which is here not at all prominent, narrow and sinuate, not touching either of the ordinary s[)Ots nor the t. p. line. Apainea liiiiata u. sp. — Ground color a powdery reddish ocher. Head and thorax innuaculate. Primaries with basal line apparently wanting. T. a. line narrow, vvhitish, evenly outcurved. T. p. narrow, whitish, even, but little outcurved over cell and rigidly oblique below. S. t. line marked by a j)receding costal shade and a series of interspaceal black dots; a brown line at base of fringes. Claviform and orbicular obsolete. Reniform a narrow white lunule, margined by black scales at the end of the cell. The veins, through the median space, are more or less evidently black powdered Secondaries very pale cop- pery, somewhat more dusky outwardly. Beneath pale, with reddish powderings. Expands l.Ol — 1.12 inches; 26 — 28 mm. Hab. — Alameda, Cal., iu June; Mt. Shasta District, Cal. (Ed- wards). 15oth sexes are before me. The species is allied to parpnripennis Grt., but the ground color is entirely different, and there is not the least chance of confusing the species. The male antennae are later- ally tufted with short bristly hair, but not serrate. Orthosia disUeha Morr. has hairy eyes, and is an Ulolonche Smith. Tt comes close to U. fasciata in type of maculation as ivell as wing form ; but besides the difference in color the contrasts are nowhere as defined, and the reniform is not discolorous, though it is well defined and of the .same form. The male genitalia agree perfectly in type with the species which I have already included in this genus (pnodesta, fascuda, niveignttata) . This seems to be oue of the cases where the sexual structure is of generic, rather than specific importance, the agreement being close in type and in details, while the ornamental characters are widely variant. Telesilla carneola n. sp. — Head and thorax a carueous or vinous gray, powdery, apparently without distinctive ornamentation, but the specimen is imperfect iu this respect. Primaries with a fine vinous red ground color, more or less evidently gray powdered, median space with a deep, blackish brown shading. Terminal space deep umber-brown. Basal line very indistinct, nar- row. composed of whitish atoms. T. a. line narrow, thread like, [lowdery, gray, slightly outcurved. T. }i. hue vague, powdery, defined rather by the difference NORTH amp:rican lepidoptera. 11] in shade between the median and subterminal space, and by short black lines on the veins, followed by minute white dots; a whitish powdering through the s. t. space, which becomes darker outwardly, shading into the deep brown terminal space. S. t. line very indistinct, broken, barely traceable, its course irregular. Fringes dark, with a grayish central line. Orbicular small, round, concolorous outlined in pale gray. Eeniform slightly constricted medially, concoloroms, out- lined by a narrow gray line. Secondaries yellow fuscous at base, becoming smoky outwardly, a pale line at base of fringes. Beneath brown, powdery, with a median line and vague discal spot on primaries. Secondaries pale basally, a broad dark extra median line and a small discal dot. Expands 1 inch ; 25 mm. Hub. — Las Vegas, N. Mex. (H. Meeskej. A single specimen from Mr. IS'eumoegen’s collection, taken by Mr. Meeske in 1889. Compared with the eastern cinereola, the present species is stouter in body, with narrower wings. The general scheme of maculation is identical, but the contrasts are much greater. While there is an evident resemblance there can be no danger of confusion with the eastern form. Dr. Harvey’s navia has a tuberculated front and anned fore tibiai, and belongs, therefore, with the Stiriin^. It may be best referred to Stibadium for the present. As Mr. Grote has recently avowed his responsibility for Dr. Har- vey’s species, the failure to see the obvious structural characters separating this species generically from cinereola, is chargeable to the former. I*liisia augiilidens n. sp.— Head, thorax and primaries bluish gray in ground color, with fuscous powderings. Collar with a median and subterminal fuscous line, and the patagise have also two rather diffuse transverse lines. Tho- racic tuft brown, basal abdominal tuft almost black, but with a white margin. Primaries with the basal line distinct, black, geminate, inwardly oblique from the costa. T. a. line inwardly oblique, with three feeble outcurves, outer line black, inner vague, and marked on the costa principally, though also traceable below internal vein ; the line is interrupted on the median vein, where, at the origin of vein 2, the greenish silver u is attached, much as in ou. A very small silver dot follows, but is completely and even widely separated. The median space is vaguely and irregularly fuscous shaded. T. p. line oblique, almost par- allel with the outer margin, irregularly aiid feebly angulate outwardly ; the line is whitish centered, the geminate defining lines fuscous. S. t. line prominent, black, irregularly and widely angulated and dentate, shading off by a fuscous tinge into the s. t. space, hut sharply contrasted against the bluish gray terminal space. This character forms the most obvious feature in the ornamentation. A fuscous shading near outer margin, forming irregular patches snbapically. Fringes gray, cut with fuscous. Orbicular a very vague, oval, oblique spot. Reniform narrow, upright concolorous, very imperfectly defined by narrow black lines. Secondaries yellowish fuscous basally, with a broad smoky brown outer 112 JOHN B. SMITH. iiiarsjin. Fringes white, cut witli fuscous. Beneath, l)otli wings yellowish, pow- ES n. gen. Eyes naked, large, globose, scarcely prominent. Head moderate, frontal vestitnre scaly, projecting, but forming a smoothly rounded sui’face. No frontal modification. Tongue moderate, corneous; palpi stout, normally noctuidous in form, reaching to the middle of front in the male, a little shorter in the female. Antenme simple in both sexes, finely ciliated laterally. Thorax small, convex, vestitnre flattened hair and scales, smooth, forming no tuftings. Abdomen smoothly scaled, untufted. Legs stout, with rather thick scaly ves- titure, tibiie not spinose, anterior unarmed. The primaries are large, l)road, with arched costa and rounded apices and outer margin. The inner margin is nearly as long as the costa. Secondaries propor- tionate. NORTH AMERICAN LERIIK^PTERA. 115 This genus has a very decided hahital resemblance to Orfhodes, but differs at once by the naked eyes. The species u]jon which tlie genus is based has been known to me for .several years. It is in the collection of the United States National iNluseum, taken as far back as 1882, and I have received it for name several times. I have tried to identify it with all genera or species to which it could have been reasonably referred, but cannot find any description to cover it, nor do I find it named in any collection thus far examined. It may be confused under Orthodes cxjnica, to which it bears some resemblance. I have named the form. Aiiorf liodes prima n. sp. — General color a soft, even mouse gray. Head and tliorax immaculate. Primaries with all the lines evident, the basal, t. a. and t. p. single, line, blackish, the s. t. broader, pale. Basal line nearly strait^ht. T. a. line with a decided inward angle on the cell, irregularly oblique below. T. p. line outcurved over cell, somewhat incurved below; it is even or slited and imnctiform; outwardly it is marked with black scales. S. t. space darkest at 1. p. line, lightening somewhat to s. t. line, which is very irregular and marked only by the contrast between the dark s. t. space and the terminal space, which is of the ground color. Fringes of ground color with a series of darker terminal dots. Orbicular wanting ; reniform large, dark, somewhat indefinite, obscured by a dusky shade, which crosses the median space and merges into the ground color at either margin. Secondaries obscurely tawny at base, becoming black at outer margin. Fringes pale luteons, almost dirty white. Beneath tawny, prima- ries with disc black, sending up an ante-apical si>ot of same color ; a black discal spot. Secondaries with a large discal spot and a deejier, brownish black outer margin. Expands .9(1 inch. ; 24 mm. Hdb. — Southern Texas. This s])ecies has two inner and three outer claws to the fore-tibia and is most nearl}^ related to brevis Grt. The contrasting white lines, the olivaceous luteons ground color and the course of the lines are difierent ; brevis seems not to have the broad median shade. A single specimen from Mr. Neumoegen. Scliiiiia digitalis n. sp. — Hesd, thorax and primaries a itowdery luteons gray. Primaries with basal and s. t. space darker, with an admixture of blackish scales; median lines narrow, pale. T. a. line evenly oulcurved, the curve greatest in the cell. T. p. line very narrow, and but very little sinuate, almost rigidly oblique. S. t. line marked by the diflereuce in shade between s. t. and terminal space, strictly parallel with the outer margin. Fringes dusky. Secondaries a pale yellowish gray with a more blacki.sh outer margin and very faint discal blotch Beneath, primaries dirty gray, with a faint reproduction of the outer lines of upper side, and a dusky discal spot; secondaries much as above. Ex- pands 1.20 inch. ; 30 mm. Hab. — Dallas, Texas. This species has heavy inner and four heavy outer claws to the anterior tibia, and is therefore related to thoreaui and rivulosa, from which it differs radically in the coloration. It is the only species with the heavy armature which has this luteons gray, almost greenish tinge. It hears a deceptive resemblance to gracilenta, and the mark- ings, indeed, are almost exactly like it. A single specimen only at hand, hut I feel (juite certain that it is in other collections as a faded gracilenta. NORTH AMERICAN LEPIDOPTERA. 129 Sohinia biiiiKliilata n. sp. — Head white, with a faint olivaceous tinge, much more marked on the thorax ; abdomen fuscous. Primaries a faintly green luteous or olivaceous, the terminal space slightly paler, else almost uniform in tint. The median lines are very distinct, broad and white; the t. a. outwardly curved and inwardly marked by a few black scales ; t. p. S-shaped, or strongly hisinuate, outwardly relieved by a few black scales. Fringes whitish, uniform in color. Secondaries faintly olivaceous, pale, with an indefinite dark outer hand, and a dusky discal spot. Beneath, primaries silver-gray, with the costal and outer margin narrowly yellowish. Secondaries white, with a faint discal spot. Expands .92 inch. ; 23 mm. Hab. — Colorado (Bruce). This haudsoiiie and strongly marked species is allied in structural characters to trifascia or cumatiiis, and is very distinct from anything I have seen. The single specimen before me is from Mr. Nenmoegen’s collec- tion, and I do not remember having had others. Scliiiiia simple.^ n. sp. — Head, thorax and primaries of a glistening, pale green color; immaculate. Secondaries a very faint ocher yellow, with an in- definite dusky discal spot, and a dusky outer margin, not extending more than two-thirds from apex to anal angle. Beneath, a glistening, pale yellowish white, with an indefinite blackish discal spot on all wings. Expands 1.20 — 1.28 inch. ; 30 — 32 ram. Hab. — Colorado. This species has a single long inner and three feebler outer, claw- like spines to the fore tibia, and it belongs to the series with trifascia and gracilenta, from all of which it differs in the immaculate prima- ries. The specimens were collected by Mr. Bruce, and are distributed in a number of collections, including that of the U. 8. Nat. Mus. The specimen before me is marked “ Denver, Light, July 21, 1887.” In the two specimens in the Museum collection, one, marked “ Foot-hills, Colo.” has entirely immaculate secondaries; the other specimen is much deeper in color throughout, and the marginal black band is much more distinct, and is complete, extending also along the costa. Scliiiiia ci'Oiiilinea. u. sp.— Head and thorax yellowish white, the thorax with an admixture of ouherous scales. Primaries whitish, with a strong ad mixture of ocherous, the maculation with a brown admixture to the ocher. A broad sub-basal, dusky band, outwardly limited by the white t. a. line, which is outwardly curved and irregularly denticulate on the veins, the widest outcurve in the submedian interspace. Inwardly this line is marked by a few black scales, outwardly it is indefinite. T. p. line white, outwardly defined by black scales, crenate, with distinct outward spurs on the veins, its general course feebly bi- sinuate. S. t. line marked by the difierence between the brownish s. t. space TRANS. AM. ENT. SOC. XVIII. (17) JUNE. 1891. 130 JOHN B. SMITH. and the even faintly oclieroiis white of the terminal space. S. t. space strongly constricted opposite cell, less so in the s. in. interspace. A row of very faint terminal dots. An upright dusky median shade, fading gradually to the ground color in each direction. Reniform an indefinite, upright, dusky line. Seconda- ries pale with a faint reddish tint deepening to a coppery red outer border. Be- neath, quite uniform co]>pery red, the secondaries paler basally, primaries im- maculate. Expands .92 inch. ;23 mm. Hab. — Southern Texas. This, in its structural characters, resembles spinosce, and in appear- ance is allied to sejicirata and saturata, the latter of which it resem- bles in the crenulate median lines and general tendency of maculation. I presume this would be a Eupanychh according to Mr. Grote, if its relation to spinosce be a generic character. Heliophaiia obliquata n. sp. — Head and thorax a rather deep clay- yellow, with an olivaceous tinge, alinost tawny; abdomen blackish. Primaries above an olivaceous, dark luteous, marked with a somewhat rusty red-brown. There is no distinct t. a. line. An oblique brown shade band extends from the inner margin near base to the end of the median cell, joining the upright some- what indefinite reniform. From this band a spur of the same color is sent to the base along the internal vein, and another along the median vein. A narrow streak runs also through the cell to the reniform. T. p. line concolorous, even, entirely parallel with the outer margin, marked by a very narrow, indefinite. l)recediug brown line, and followed and defined by the brown s. t. space. S. t. space uniformly brown, marking the s. t. line by the contrast between it and the terminal space. This line of contrast is irregularly bisinuate. A brown terminal line at the base of the concolorous fringes. Secondaries black, mingled with the tawny yellow basally, the fringes tawny. Beneath, primaries black, costal and outer margin tawny, the former allowing part of a black discal mark to be visible. Secondaries with co.stal third and centre tawny, else black. A large black discal spot. Expands .75 inch. ; 19 mm. Hab. — Texas (Neumoegeii). I have had several examples of this little species for determinatiou, some of them I thiuk from Colorado, but have not named it any- where. The characters agree well with those of the genus as given by me (Trans. Am. Ent. Soc. x, 240). It is not impossible that this is an extreme variety of Mr. Grote’s species, but both upper and under side differ from the description and from the specimens I have seen. In mitis the ground color is dark, while in the jiresent species it is pale ; but this reversal does not necessarily indicate absolute difference. Ileliopliaiia amaryllis n. sp. — Head, thorax and abdomen black, with fine, thin, loose, divergent, pale yellowish vestiture. Primaries a dirty grayish brown, median sjiace a dirty yellowish white. Basal line distinct, whitish, mar- gined by black. T. a. line whitish, i)receded by a black, and followed by a dark NORTH AMERICAN LERI DOPTER A. 131 gray shade ; in course it is obtusely angulate on the median vein, and in the slight convexity in the cell, the round orbicular rests on the line. T. p. line whitish, even, widely outcurved over the cell and incurved beneath: defined outwardly l>y the dark ground color, inwardly by a narrow gray-brown line. The reniform is large, black, filling the entire width of the cell and resting on the incurve of the t. p. line. A narrow dusky shade from the reniform to hind margin close to t. p line. Beyond the t. p. line the wing is uniform in color, somewhat white marked on the veins and crossed by the narrow whitish s. t. line, which is twice outcurved and with three acute inward teeth. Secondaries black, with a broad whitish hand, almost divided by the large black discal spot, Beneath, primaries white, with a broad, irregular, black outer border, a broad black basal dash, and a large black reniform. orbicular and subapical spot. Sec- ondaries much as above, but median white band broader. Expands .80 inches ; •20 mm. Hah. — Colton, Cal. I have seen but a single specimen of this curious insect, received from INIr. W. N. Tallant, Columbus, Ohio, marked collected by G. R. Pilate. It has the habitus of Melieleptria, but the structure of the genus to which I have referred it. STYLOPODA n gen. Eyes narrowed, ovate, naked. Head small, not retracted, front somewhat protuberant, conical, but not roughened. Tongue strong, moderate in length. Palpi reaching to middle of frf)Ut, stout, the terminal joint small, the parts so held as to make the front seem pointed. Anteniue moderate in length, in the S finely ciliated. Thorax plump, robust, vestiture scaly, smooth, forming an indefinite posterior tuft. Legs short and stout, tibiie not spinose, the spurs long, clothed with long, divergent vestiture, anterior sho)-t, broad, flattened and corneous at tip, with a long inner and short outer claw- like spur or process. Abdomen short, conic, nntufted. Primaries short, broad, costa somewhat de|)ressed, making the apices prominent. This genus resembles Pseudotamila in structure, save that the tibiie are not spinose, and the primaries have the costa de|)ressed. Its characters are also like F.^eudacontla, save that the eyes are narrow, ovate. The genus is recognizable, and unlike any other of our Heliothid foi'ins known to me. Ktylopoilsi eeplialica !i. sp. — Head, thorax and abdomen deep piir])li.^h blaek. Primaries purplish hlack to t. p. line, then an irregular white shade fading into the black ground color beyond. The macnlation on the inirjtlish ground is picked out by deep black scales. Basal line single, complete. T. a. line .single, fine, upright or slightly oblique, very regularly tridentate. T. p. line single, outwardly oblique from costa over reniform. then very deeply indrawn. 132 JOHN B. SMITH. UHTrowine; the median space by fully one-half below vein 2. This line is em- phasized by the pure white following shade, which is broadest in the suhmedian interspace, white scales — seeming bluish on the back ground — extending through the subterrainal space and on costa, vaguely indicating the s. t. line. An inter- rupted black terminal line. Claviform apparently wanting. Orbicular moderate, concolorous, round, black-ringed. Eeniform incomplete, apparently only the inner margin defined, the outer merged in the white shade. Secondaries black, with white fringes. Beneath black, primaries with an interrupted white baud. Expands .68 — .72 inches; 17 — 13 mm. Hab. — California. Two specimens ( 9 ) are in the National Mnsenm, one from my old collection, the other “ through C. V. Riley, 1888," collected by Coquillet. The latter is perfect so far as maculation goes, but the legs are deficient. The former is somewhat rubbed, and has no legs at all. This is a strongly marked form which there should not be any difficulty in recognizing. There is a single male specimen from my collection in the Museum, also from California, which is congeneric, but which is almost too poor to serve as a ty]>e. The [)rimaries above have been rubbed almost bare of scales, and no maculation is traceable. The secon- daries are black. Beneath, the primaries are carmine-red, the secon- daries black. If this is in any collection, I should like to get good specimens. l*seiiattern of maculation, but the black is replaced by an ocherous brown on primaries, and the median white band of secondaries broadens and becoming inwardly diffuse, lightens the base. The type is from Nebraska, and I have seen no other specimens. It may be we have to do here with another species, but without more ma- terial I prefer to leave it as a geographical race or form. Mefopoiiia macula sp. nov. — Head, thorax and primaries orange-yel- low. Head and collar with an admixture of brown. Primaries with a purplish blotch filling the base of discal cell, and narrowly connected along the median vein with a darker, irregular blotch, whose outer margin is about where the t. p. line should be were it present; a small, irregular spot, marks the location of the accessory cell. The inception of the s. t. line is marked by a small, some- what ferruginous preceding patch, and below that by a series of four or five irregularly separated venular dots. Two dots below the basal purple blotch mark the t. a. line. Fringes cut with purplish. Ordinary spots entirely obsolete.

Beneath, primaries blackish, costa and fringes yellow; secondaries yellowish, with an outer darker line- Expands 1 inch ; 25 mm. Hab. — Las Vegas, N. Mex. Oltviously distinct, from the described species by the black secon- daries with contrasting yellow fringes. The clypeal structure is a cup-shaped depression, from which rises a cylindrical projection also cupped at tip. Specimens taken by Mr. Meeske are in the collections of Neumoegen and Hulst. ACJROTirHII.A Grt. This genus was proposed by Mr. Grote (Ann. Lyc. 1875, xi, 107) for Mr. Morrison’s Agrotis montuna, and the genus is, in my opinion, a good one, diflering from Agrotis in the narrow, reniform eyes, the retracted head and anartijorm habitus. To this must come FacJmobia alaske Grt., of which there is a specimen in the U. S. Museum, easily recognizable by the discolorous claviform. Among the species never recognized by Mr. Grote is Moeschler’s Agrotis stanclingeri (Wien. Eut. Monatsch. vi, 132, pi. 1, fig. 4, May, 1862). To the courtesy of Mr. Moeschler I owed a chance to ex- amine his type, and found it to be in all respects like Morrison s species. The figure is accurate, and there is no doubt at all that staudingeri must replace montana in the lists. INIorrison described his species from Colorado, July 22d to August 12th, 12,000 feet. Afterward the species was received from Mt. Washington, and Labrador is now added to the distribution. In the collections made by Mr. Bruce there is a species which I at first considered the same as that described by Morrison, but which offers a number of constant points of difference, which I think justify a new species fully congeneric with staudingeri. Agrotipliila. colora*lo n. sp. — Ground color of head, thorax and prima- ries an olivaceous luteous, or ocherous brown, the variation being quite consid- erable. Front with a strong admixture of white hair, forming a white margin to the eyes. Collar black centred with a whitish basal and terminal margin. Patagife white margined. Abdomen blackish, wdth fine w-hite or pale yellow hair. Basal line black, single, outwardly margined with white. A curved black streak crossing the basal space on the internal vein, margined above with white, and this with the white inner margin to the t. a. line makes a quadrate space at base, the angles all extended. T. a. line incurved, the lower curve long and reaching nearly to the middle of the inner margin. T. p. line with an even outcurve, nearly parallel with outer margin ; inner line composed of connected, black lunules, outer Hue a broad whitish shade. S. t. line white, ditluse, pre- 134 JOHN B. SMITH. ceded by a series of more or less confluent sagittate l)lack spots, broadly inter- ruiited sut)apically. A dusky line at base of fringes. .\ll the veins white marked ; a mere trace of claviform. Orl)icular large, irregularly ov'al, black margined, inwardly white ringed, centre pale. Eeniform large, kidney-shaped, narrowly black ringed, inwardly white margined, centre pale. The space between these ordinary spots is blackish, and there is a black spur from reniform to t. p. line. Secondaries blackish fuscous to blackish, with white fringes. Beneath whitish, both wings with narrow dusky margins and linear discal spots. Breast blackish, legs with fine, thin, white hair. Antennte of male with whitish cilise. Expands 1.16 — 1.24 inches: 29—31 mm. Hah. — Colorado, Bruce. Both sexes of this species are before me from i\Ir. Bruce’s collec- tions. There is considerable difference in the general appearance of the sexes, though not in details of maculation. The male is the smaller, and is sordid, more pale and less definitely marked ; in the female the ground color is deeper, richer, and the white contrasts very much more distinctly. Comjiared with staudingeri, this species is larger, the claviform is barely marked, and the orbicular is different in shape, large and irregularly oval in this species, small and round in stemdingeri. The species is in Mr. Neumoegen’s collection, and I have seen others from Mr. Bruce. A good pair in the National Museum collection among others. .\grotipliila rigida n. sp. — Head, thorax and primaries dull fuscous brown, with a yellowish admixture in the hasal and s. t. spaces. Front with pale scales intermixed. Basal line evident, black, followed by a white shade. T. a. line rigid, slightly oblique outwardly, white inwardly, margined outwardly by black, which is a little extended on the veins. T. p. line outcurved over cell, thence nearly parallel with outer margin ; inner line black, a little out- wardly denticulate on the veins, followed by a rather diffuse whitish shade. The veins are pale marked through the s. t. space, and aid in defining the series of dusky, sagittate spots before the s. t. line. This latter is whitish yellow, rather broad, distinct, very even, a little outwardly bent only on veins 3 and 4, a blackish, interrupted terminal line. Claviform rather obscure, incompletely outlined, concolorous. followed by a distinct yellowish shade, which extends to the t. p. line. Orbicular small, oval, slightly oblique, black margined, pale ringed, and wifli concolorous centre. Eeniform moderate, kidney-shaped, pale ringed, with narrow black margin and concolorous centre. Secondaries smoky fuscous, somewhat paler basally, with a dusky discal lunule. Beneath whitish, powdery, with a common, broad, blackish, e.xtra median band : a discal spot on all wings; primaries with a faint, dusky, submarginal band and secondaries, with a dusky outer margin. Exi)ands 1 inch ; 2.5 mm. llab. — Colorado ( Bruce). A single specimen of this species, from ]\Ir. Neumoegen’s collection, is before me, and is in good condition. NORTH AMERICAN LEFIDOPTERA. 135 This is one of the most interesting species I have studied, and will not remain in the genus in which I have placed it despite its strong habital resemblance to both standingeri and Colorado. The eyes, while narrowed, are scarcely as constricted as in the type of the genus, the fore tibiie are somewhat flattened and very heavily armed, with longer sjiines at tip, and, finally, the front shows quite a long, conic, corneous |)rojection, which is evident in neither of the other species. It really agrees better with my genus Chorizagrotis, but the form is not depressed, the eyes are narrowed, and the fi’ontal jirotuberance is quite different. It has little or no habital resem- blance with Chorizagrotis, and I think it best referi-ed for the j)resent to the genus which in appearance it most resembles.

FOX. On the species of TRYPOX V1.01V inliabitiiig America Xortli of Mexico. BY WILLIAM J. FOX. Through the kindness of Mr. E. T. Cresson, I have had the op- portunity of working over this interesting genus of Fossorial Hy- inenoptera. I do not offer any suggestion as to the proper position of this genus, which has been placed in the Larridse by most Euro- pean authors. Mr. Cresson has placed it in the Crabronidie, where I prefer to leave it for the present at least. Herein eight new species have been described, also two from Cuba and Mexico, res|)ectively, have been added to our fauna. The species are, as a rule, easily distinguished, presenting characters which are readily seen. The types of all the species herein described as new, with the exception of T. Johmotii (which is from my collection), and several of Pack- ard’s, will be found in the collection of the American Entomological Society. The species are distinguished as follows : Females. Metanotum not trisulcate. Abrloiiieii entirely black. Metanotum punctured. Wings blue-black; thorax clothed with black pile albilarse. Wings with the anterior pair only fuscous, the posterior ones hyaline, except apical margin; thorax witli pale pubescence. albipilo>«niu. Wings hyaline, their apical margin and the marginal cell fuscous; thorax and abdomen with silvery pile excavafiini. Metanotum with an enclosed space.

In Enclea the second subcostal venule arises just beyond the end of the discal cell, remote from the origin of the first subcostal, w'bile tbe first and second median venules arise as far apart as the second and third ; in Parasa the second subcostal venule arises just within the cell, close to the first subcostal, and the first and second median venules ari.se almost from a common point. Otherwise the venation is the same. In the fore wings the s.-c. vein is remote from the costa and the costal arises from its base; five s.-c. nervules, tbe origins of the third and fifth approximately trisecting the vein beyond the cell; discal cross-vein twice angulated, the independent vein arising from its upper third ; a bifid false discal vein ; median four-branched ; submedian present ; internal bifid at base. The hind wings have the same venation in both genera. Mr. E. L. Graef has very kindly loaned me his specimens of these genera which comprise nearly all the species, and, from an examina- tion of them, I have been enabled to complete this paper. The species mav be separated in the following manner: Thorax l>rown Genus Eiiclea. Green of primaries not covering cell.

Primaries: costa sti’aiglit, ape.x subacute, outer margin convex, inner margin nearly straight, then rounded to base. Dark glossy vval nut-brown, darker than cippus (of the same color as some Florida examjiles of cippus), a very small round black discal dot in the cell, not elongated as in cippus. Tw'o pea-green patches of considerable size, both rouTided and edged outwardly and below with silvery white and black. The larger patch occupies the space below the cell, not reach- ing the base of the wing and narrowly sejtarated from the internal margin, rect- angularly excavated op))Osite the outer third of the margin, the sinus partly filled in with a patch of orange ferruginous scales that tends to be bisected on the snbmedian vein. The patch extends beyond the end of the green patch, reaqhing the obsolete subterminal line, which is lost in the ground color. The other green patch is almost circular, in one example produced inwardly a little above the discal dot. It is very narrowly separated from the fir.st jiatch and almost reaches the costa. It represents the snbapical patch of cippus. Imt shows no tendency to become divided. It is follow’ed by the usual orange ferniginons patch, trisected by the uervnies and reaching the obsolete subterniinal line. Fringes concolorous with primaries, interlined with paler at the base. Secondaries scarcely paler than primaries, concolorous.

I cannot find that this sjiecies has been figured or described before. 1 have seen it in collections labeled querceti and qaercicola, but it does not correspond at all with Herrich-Schtlfier’s figure of the.se forms. It difiers from E. cippus var. moidtor in its smaller size, round, minute, discal dot ; the green spots being rounded and not triangular, the lower elliptical, less deeply excavated than in cippus, the upper almost circular, not divided. The red patches are smaller than in cippus, and are distinctly divided by the veins. Euclea ferruginea Packard. 1864. — Pack. Proc. Ent. Soc. Phil. Hi, 338. This species is fnarked like E. vur. delphinii, but has in addition a ferruginous patch beyond the suhterminal band. It is closely allied to E. cippus. The following is Dr. Packard’s descriittion : "% more reddish than the other species. . . . Basal green spot small, slightly indented externally. Middle snbai)ical spot” [of the three snbapical green spots which are very variable, often confluent] “large; lower one obsolete, with a few scales connecting it with the reddish discal spot, which is margined above with brown. Beyond the green spots the wing is suffused with rust-red. of a lighter blue than any of the other species. Outer edge darker, like the costa. Beneath both wings are alike, almost testaceous.

Head whitish, labrum and sutures of clypeus yellowish ; ocelli black ; jaws dark brown ; retracted beneath joint 2.

The spines are short, black, and arise from conical bases. Another lateral row of spinous tubercles beginning on joint 3, those on joints G to 12 situated above the spiracles (none on joint 5) the one on joint 4 about as long as the subdorsal one, the others of uniform length, longer and rather slenderer than the short subdoi-sal ones.

I have had some doubt about referring the species to at all, as I have never seen a specimen that exactly corresponds to Cramer’s figui-e in which the greeTi band is broken into three triangular spots: but this may occur. The figure is too poor to base critical remarks upon, but it seems extremely ju’obable that it is the present species that was intended.

The head is retracted within joint 2, and this in turn under joint 3. There is a double row of blackish impressed spots in the dorsal region and elliptical depressions on the sides, but the skin is nearly uniform, soft and smooth. Color greenish brown, lighter, more red- dish posteriorly, shaded on the dorsum with dark orange ; a number of indistinct, brighter waved lines. Below colorless, bordered by a salmon colored band. ® Mr. Henry Edwards has called my attention to a fact which I have recently verified, viz., that Herrich-Schafler’s figure of chloris represents the species known as Parasa fraterna Grote. Hence the synonymy will have to be altered as above. NORTH AMERICAN LEPIDOPTERA. 155 Closely related to Euclea is the genus Adoneta Clem., but in our lists it has not been associated with its allies. It differs from Euclea in the shorter pectinations of the autenme of the male and the more slender body. The shape of the wings and pattern of maculation are the same, but the venation diffei’s in that Adoneta has but four subcostal venules, while Euclea has five in the fore wings, and the subcostal vein in the hind wings divides nearer the tip of the wing in Adoneta. These are all weak characters. The larvse are of the same structural type in both genera, but that of Adoneta is more highly colored. From a consideration of characters, drawn principally from the larva, I would arrange the genera of the Cochlidiie somewhat as follows, omitting the genera of which I do not know the larva ; L. flexuosa and L. coesonia of Grote, do not belong to Lhnacodes, and will probably have to be referred to Heterogenea or an allied genus, as, indeed, Mr. Grote has himself suggested.* Varina ornata Neum., in my opinion, does not belong to the Coch- lidiie.f I have examined a 9 specimen which Mr. Graef has kindly loaned me, and a % from Prof Smith. If the moth is a bombycid at all, it will have to be referred to the Dasychirie as its characters exclude it from the other subfamilies. I wmuld add the following characters to Mr. Neumoegen’s description of the genus : Primaries 12-veiued ; internal vein not furcate at base; median 4-branclied, vein 5 nearer to 4 than 4 to 3 at base ; cell open ; 6 arising from cross-vein near the subcostal; a small, narrow accessory cell; 7 from 8 immediately beyond accessory cell ; 8 and 10 together from end of accessory cell ; 9 from 8. rather more than half as long as 8. In the secondaries 3 and 4 arise together from the end of the median ; cell open ; 5 absent, represented by a fold ; 7 from 6 beyond the end of cell ; 8 touches the subcostal at about one-sixth the length of cell from base Tongue present, but weak ; ocelli small. The thorax is covered with scales and hair, and not hair alone, as Mr. Neumoegen states. A knowledge of the larva of V- ornata is much to be desired. * New Check List, page 63. I think that csesonia may prove to be synonymous with Heterogenea shurtleffii Pack. Flexuosa is congeneric, and may be only a form of csesonia. t See Mrs. Slossou, Ent. .Amer. vi, 136.

This genus was characterized by Dr. Packard, in 1864, f as Cyrtosiu, but this name, being preoccupied, was sub.sequently changed by Grote and Robinson. The species are subject to considerable variation, and are usually rare. I have examined the male genitalia of three species and I cannot find that they offer any characters to afibrd specific separa- tion. The supra-anal plate in all narrows ra]fidly, and is extended backward in a long, evTii, narrow prolongation that slopes downward without curving, being pilose beneath. It resembles the same part in Datana, but is much less strongly bent down. The side pieces are simple, concave inwardly, slightly tapering, the ends rounded. The larvie are small green Limacodes, much resembling Parasa fra- terna in general shape, but lacking the spinose subdorsal tubercles, 'fhe end of the body is ])roduced into a little “ tail” as in Parasa, which is often marked with red above, and this constitutes the only colored marking. They feed on the leaves of any deciduous tree, usually frequenting the central or more shaded parts of the woods. Only one brood occurs each year in New York, the larv’je maturing in September. Dr. Packard has kindly allowed me to see his material in this genus, and I believe the following arrangement of species corresponds with his opinion. *• See Butler, Ann. Mag. N.

Curiously enough this species has been omitted from both the Brooklyn Check List ami Mr. Grote’s New Check List, as well as from Mr. Hy. Edwards’ additions to the same (Ent. Amer. vol. iiij. I*ack:irecies in the Cambridge Museum ; as well as the results of his observations on the genus for many years back. Through the favor of Prof. C. V. Riley, I have been entrusted with the col- lection of the National Museum. To Mr. Frederick Blanchard I owe many valuable suggestions and sets of the species living on the Concord River. To Messrs. Roberts, Liebeck, Westcott, Wickham, Hulbert and Sherman, my thanks are due for specimens. Finally, my friends on Staten Island, William T. Davis and J. C. Thompson, have freely given me the use of their collections and time. Before using the synopsis, the reader should observe the following explanation of the terms employed. “ Elytra truncate at tip, or subtruncate.” Under this head are included all the forms that are in the least truncate, or even doubt- 160 CHARLES W. LENG. fully SO, and the only form excluded is that in which the tip is evi- dently rounded. In such the sutural margin is sinuate. “ Mesosternum narrower than the coxa.” By this is meant that the portion of the under surface seen between the middle coxjb is narrower than those coxre separately. It is used as a convenient measure of the width of the insect, being narrowest in the conspicu- ously slender species, and may be inferred where it is difficult to see, as when the insect is pasted on a point. “ Sutural margin sinuate posteriorly.” In many Donacite the elytra are declivous at the apex ; the elytra are closely joined at the suture in repose, but the margins on the declivous portion appear double, and although they truly meet, there is a second apparent mar- gin within the true one. This second margin, starting not more than one-fourth the length from the tip — often less — is sinuate, or curved more or less, away from the suture. Thus a space somewhat ellip- tical in shape is formed, sometimes depressed, sometimes in the same plane with the rest of the elytron, and always destitute of punctua- tion. This sinuation might also be described as a sinuate displace- ment of the sutural stria. “ Posterior femora elliptical.” In all Donacise but ru/a, the j)os- terior femora are decidedly pedunculate. In that species the neck is not evident, and I have followed Dr. LeConte’s use of the term elliptical to describe them, though they are actually much broader at the apex. Certain characters are subject to great individual variation. These are the color, the relative length of the antennal joints, the number and size of the femoral teeth or spines, and the punctuation and sculpture of the upper surface. While diherences in these respects are, to an extent, indicative of specific rank, it is important that they be not carried too far, and I have endeavored to mark their limits in the descriptions which follow the synopsis. The dilation or extension into spinous ])rocesses of the tibiae is very evident in some species. In pis^eatrix and jKilmata this is esj)e- cially true of the middle tibiae, ami a spinule may also be seen beneath the dilation. In certain of the convex species the dilation is more apparent on the front tibiae. The character, however, varies greatly in individuals of the same species, and I have not made use of it in the synojLsis. The sexes in most Donaciae are widely differentiated. As a rule the females are broader, the posterior femora are either without or NORTH AMERICAN COLEOPTERA. 161 with fewer and weaker spines than the male, and the last dorsal segment is rounded at ajiex and more or less elongate. The males besides being narrower and more strongly armed on the femora, have the pygidium shorter and either truncate, arcuately emarginate, or acutely triangularly emarginate, but never rounded. The males of palmata have the anterior tarsi dilated, and the same sex of piscatrix has the first ventral segment excavated. All the species of Donacia are subaquatic in habit, frequenting either the pond lilies, on the broad leaves of which they may be seen from A{)ril to Septendier, or the rushes and sedges that grow in danqi places. In the following synoptic table several new names will be noted ; these are : cmcticornis Newn., which was formerly called lucida Lac., or in the check lists rugifrons Newn. pusilla Say, which antedates and replaces cuprea Ky. rufa Say, which antedates and replaces Kirbyi Lac. The scheme proposed is as follows : Head and thorax evidently pubescent above Group A. Head occasionally, thorax never pubescent. Elytra truncate at tip, or subtruncate. Form decidedly flattened ; mesosternum about as broad as each coxa. Group B. Form more convex; mesosternum narrower than the coxa Group C. Elytra rounded at tip, the sutural marsin sinuate posteriorly; form convex; mesosternum narrow Group D. Group A. Three species fall into this group which are not otherwise at all similar. It will be noted puhes^cens is the only species with pu- bescent elytra, and puhicollis the only one with the femora destitute of teeth or spines in both sexes. A badly rubbed specimen of hir- ticollis might be placed in the next group, from all the species of which it may be distinguished by the very small tooth of the femora, which is often reduced to a mere lump. The species are separated thus : Elytra without pubescence; posterior femora with a small tooth. ..liirticolli;S. Elytra without pubescence; posterior femora simple ptibicollis.

The s]iecies comprised in this grou]) are similar in appearance, all being evidently flattened above ; the first ventral segment is not only flattened, but longer than all the others combined ; the color is frequently testaceous ; the middle tibite are expanded at tip and are armed beneath with a spinule ; the mesosternum is conspicuously broad in all excej)t piscatrix male. These are the species which frequent the pond lilies, and Mr. Blanchard has suggested that their great breadth of beam indicates an adaptation to their particularly aquatic existence, in which connection it is worthy of note that the ])ubescence of the under surface, characteristic of the tribe, is in them especially develojied. The species are : Thorax narrowed in front; posterior femora plnridentate male, simple female. floridte. Thorax quadrate, or wider in front; posterior femora dentate in both sexes, the male often hi- or tridentate. Auteunffi with second and third joints nearly equal ciiicticoriiis. Auteuuffi with third joint much longer than second. Elytra truncate. Anterior tarsi of male dilated palinata. .Anterior tarsi simple liypoleiica. Elytra subtruucate, form more convex; first ventral segment of % exca- vated piscatri.x. The specimens which I include under the name cincUcornis may be divided into three species or varieties or races as follows: Prothorax not coarsely punctate. Posterior femora male very large and strongly dentate, posterior tibiae curved and serrate lucida. Posterior femora less developed unnamed. Prothorax punctate at base and apex only; posterior femora less developed. tibiae straight, or nearly so proxima. Prothorax coarsely punctate over its entire surface ; femora and tibiai as in pre- ceding magnifica. From the number of specimens before me, showing all gradations in the thoracic sculpture and femoral armature, I do not think these forms can be recognized as species, and I suggest that they be placed in our lists as varieties. Group C. 'fhis group includes subtilis, of which the female might, with equal propriety, be placed in the preceding group, though the male is de- cidedly more convex ; and several species which, by their convex form, are associated with the last group, l)ut differ in the truncate NORTH AMERICAN COLEOPTERA. 163 elytral tip. Two species, Harrisu and distincta, present also the peculiar sinuation of the sutural margin of the elytra which charac- terizes that group. This consists in the displacement of the margin for a space equal to one-fourth the length of the elytron, whereby, wdien the elytra are closed in i-epose, an elliptical space is formed hounded by the displaced margins. In Harrisii the margin appears double, and the inner sinuate portion is in a higher plane than the outer straight portion. In most of the species the material which fills the sinuation is in the same plane. Eyes of normal size; sutural margin of elytra straight, except in distincta. Thorax punctate, not or scarcely tuberculate. Thoracic punctures coarse, uniform siiblilis. Thoracic punctures uneven, finer punctures mixed through the coarser. poroi^ioollis. Thorax uneven on the disc, tuberculate on the sides. Sutural margin of elytra straight. Elytra with two transverse indentations cPqiialis. Elytra not indented ; posterior femora male dentate, female simple. t II bore II lata. Sutural margin of elytra sinuate distincta. Eyes small; thorax tuberculate; sutural margin of elytra sinuate.... Harrisii. Of these species, porosicolUs seems rare ; the specimens I have are far more slender than any other, and there is an appearance of an abrupt demarkation on the sides of the elytra. Inasmuch as siibtilis, its nearest ally, is constant in the style of its punctuation, I have preferred to use that character for the separation of the two species. 1'he specimens under subiilis may be separated thus : Thorax straight on the sides; second and third antennal joints subequal. Thorax constricted at middle ; third joint of antennse longer than second,..r!tgos«. but on account of the variations observed in these characters in other species, I doubt rugosa being a distinct species ; torosa Lee. is included with distincta. Group D. The species here included are readily distinguished by the convex form, rounded elytra and sinuate sutural margin. They may be se])arated as follows : Thorax depre.ssed without basal and medial groove. Posterior femora dentate in both sexes piisilla. Posterior femora dentate in male only Icinoralis. Thorax convex, punctured, and with an evident basal and more or less evident medial groove. 164 CHARLES W. LENG. Posterior femora pednncnlate ; thorax closely punctulate.

Legs rufo-testaceous ; posterior femora dentate in both sexes flavipoN. Posterior femora elliptical ; dentate in both sexes; thorax sparsely punctured ; legs rufo-testaceous riifa. Tlie species contained in this group may be arranged in jtairs as placed above ; the differences, however, between pudlla and /(?Hior«^hs, emcirginata and metallica, jiavi2)es and rufa, are feeble. The first pair are readily isolated by the depressed thorax, the second by the dark legs, the third by the yellow legs and more convex thorax. It must be observed that the femoral tooth is less developed in the females throughout the genus, and is particularly weak in this group ; femora are subject to some variation in form and the punctuation is inconstant in many of the preceding species, so that, while the con- siderable number of specimens before me are separable by the char- acters given, the reader must be prepared to find some which, in these respects, will vary from the tyj)ical form.

I cannot find any description agreeing with the characters of this insect. It looks like a small lucida, but differs not only in the sim- ple femora of the female, but in the form of the thorax. I have seen only three specimens, in the National Museum. I>. ciiicticoriiis Newman. Original description translated. “Antenme elongate, the basal joint pale, the apical black: vertex shining; prothorax quadrate, most minutely punctured, with an impressed dorsal line; head and prothorax black seneous, elytra testaceous, shining; elytral apex trun- cate; metafemora elongate, incrassate, bidentate; legs testaceous, femora with two black vittae. [Corp. long. .325 nnc., lat. .1 unc.] This species has been long known as lucida Lac. The synonymy was pointed out by Dr. Horn some time ago, [lint. Am. I, p. 9] but has not been corrected in the Check List. Lacordaire’s descri[)tion of lucida is as follows ; “Moderately elongate, above metallic green, very shining, elytra rufe.scent; beneath densely cinereo-sericeous ; antennte and legs rufous, maculate with black ; protborax transverse, slightly narrowed behind, the angles obtuse but distinct, the margin in front and at the middle of the base, reflexed ; towards tbe front on each side obsoletely tuberculate; above vaguely rugose, with a dorsal sulcus abbreviated behind and an impressed puncture; elytra flattened on the disc, declivous at apex, which is squarely truncate; bi-impressed, punctato- striate, interstices flat, vaguely transversely rugose.

This is au abundant and very variable species ; it is the species called rugifrons Newn. in many collections, which name was applied NORTH AMERICAN COLEOPTERA. 167 to an entirely ditierent insect belonging to the last group. The va- riations observed are in size, as indicated above ; in color, which may be a uniform greenish black, or a much lighter color almost testace- ous, or a combination of both ; in the femoral teeth, which depend in number and size upon the development of the insect, and may be traced through gradually weakening forms, from three prominent spines in the male to a single obtuse tooth in the female ; and in the relative length of the antennal joints, the third being usually as short as the second, but sometimes evidently longer. It is never twTce as long, however, as in the following species. Although se- lected specimens can be made to look very different, I can find no character in these variations to base even a variety. With the punctuation of the thorax, it is somewhat different. In- termediate specimens do occur, and indicate the close relation be- tw’een cincticornis and its varieties proxima and magnijica, but the greater number are readily separated, as indicated in the synopsis. Food-plant is undoubtedly the pond lily, Nuphar advena. I have always found the insect on this plant, frequently within its yellow flowers, and Mr. Roberts has also in Vermont, and Mr. Blanchard in Massachusetts. Furthermore, it does not occur in localities where there are no lily ponds. The white water lily, Nymphcea odorata, occurs in many ])onds with the Nuphar, and the insects show no partiality for it in the imago stage. The original descriptions of the varieties are : Var. proxiina Kirby. — “Thighs bidentate, witli one tooth minute; above dark violet glossy, head rather bronzed ; punctures of the elytra green gilt; body underneath covered with a satin silver pile.

Head a little bronzed, channeled between the eyes, minutely punctured, palpi testaceous ; antennae entirely black ; prothorax in the disc dark violet and channeled, sides bronzed and impressed, anterior tubercles not prominent; scutellum bronzed ; elytra nearly black, with a slight tint of violet, punctures green gilt, interstices of the rows not wrinkled, an anterior impression near the suture, rounded at the apex; posterior legs long, with the thighs somewhat curved, attenuated at the base, curved at the apex, with two teeth placed consecutively, the first long, slender and acute; the last wide, short and denticulated posteriorly. This species is nearly related to cras- sipes Fab., but the antenuse and legs are entirely black, and the teeth on the posterior thighs are not equal.” Length 8 — 11 mm. ; .32 — .44 inch.

Varies in color from the typical “ pale rufous” to a dark bronze just as the preceding species do; alutacea Lee. is the name ap{)lied to the darker forms in many collections, but it is impossible to draw any line between them. The intermediate forms are among the most beautiful specimens in the genus, the suture being broadly bronzed and the other part of the elytra golden testaceous. This species occurs with the preceding on the leaves and in the dowers of Nuphar, and I have taken it on the roots of that plant, where it pupates, enclosed in an oval cocoon of leathery consistency.

This species is very abuiulunt on Staten Island at a jtond Itordered l)y marshy ground, where grow a nninber of sedges and grasses, on whicli the insects principally occur. They wander to the lilv pads, but do not occur in ponds where the lilies alone are abundant. I therefore conclude that they live on these sedges. Mr. Clarence M. Weed has noted their abundance in a similar situation in Ohio ( Bull. Ohio Ex. Station, 1889). Var. rugosa Lee. — Differs only as stated in the synopsis.

The color varies from briglit reddish or cupreous, through many shades of metallic color, to a form nearly black. The legs are yel- low or rufous in the majority of specimens ; in a few they are nearly black, and constitute the variety pyritosa Lee. The relative length of the antennal joints is not constant, and will not serve to separate pyritosa, as a species, as stated by Mr. Crotch. From some variation observed in the specimens before me, I am doubtful if it is a sufficiently defined variety even to be con- tinued in the list. The indentations of the elytra are somewhat variable in depth and consequent distinctness, but are never very marked. The species is sometimes mixed in collections with CBqualis Say, and the depth of these indentations afford a convenient index for their separation. Length 6—8 mm. ; .24 — .32 inch. Habitat. — Hud.

Original description. “Dull metallic rufous, front destitute of lateral impressed lines. Body totally dull rufous with a metallic gloss, particularly on the elytra. Head dusky, almost opaque, with much crowded, very small punctures, no appearance of tubercles, a very distinct impressed frontal line extending down between the antenufe, no appearance of impressed lines near the eyes; anteunse somewhat paler than the body, third joint longer than second ; thorax longer than broad, minutely punc- tured, longitudinal line very distinct, a transverse impressed line on the posterior submargin, lateral tubercles rather prominent, obtuse, tubercle of the anterior angle distinct from the large tubercle, acute, elytra hardly obviously inequal near the suture, with strise of punctures, tip decurved, almost truncated, or ob- tusely rounded; beneath, in a particular light, dull silvery sericeous, feet rufous. Length more than 3-16 inch.” AVith this species must be united Kirhyi Lac., described as follows : “ Thorax convex, legs short and stout, posterior femora elliptical, armed be- neath with a strong tooth, not attenuate at base. Subelongate, cupreo-seneous, shining; thorax sparsely punctate cordate, angles rounded, lateral tubercles dis- tinct, but barely prominent, a slight channel before the base strongly impressed ; elytra scarcely rugose, interstices flat, impressed before the middle; legs and autennse rufous, third joint half as long again as the second, the fourth a little shorter. Long. .28. 6a. Varies with the thoracic tubercle less distinct.” Mesosternum, etc., as in the preceding, and the sexual characters are the same. No variations are observed in color, and the insect is readily known by the con- vex shining thorax almost destitute of punctuation. Length 7 — 7i mm.; .28 —.30 inch. Habitat — Can., N. H., Mass., N. Y., Ohio, and one specimen is labeled “Texas.” Apparently more rare, the collections examined containing to- gether sixteen specimens. Synonymy and Bibliography. The greater part of the following synonymy is derived from the “ Catalogus” of Gemminger and Harold, from Dr. LeConte’s Syn- oj)sis, or from Mr. Crotch’s paper. Of the remainder a part is due to comparisons made by Dr. Horn with the LeConte types at Cam- bridge, and the balance is the result of a comparison of the published descriptions. All the older names have been recognized, and in some instances those which have been in use have had to give way to them. 176 CHARLES W. LENG. D. hirticollis Kirby, 1837, Faun. Bor.

NORTH AMERICAN COLEOPTERA. 177 Kovi!«ion of the g;eiiera and species of AISTHOXOMIRJI iiiliabitiiig North America. BY WILLIAM G. DIETZ, M. D. iSince the publication of “ The Rhynchophora,” (Proc. Anier. Philos. Soc. 1876) but few new species belonging to the tribe under consideration have been described, while the amount of material ac- cumulated in our collections has been considerable. It was my in- tention, originally, to confine the following essay to Anthonomus proper ; the discovery, however, of new and im})ortant characters, as well as a greater appreciation of others heretofore deemed of but secondary importance in the classification of genera of this tribe, has led me, step by step, to include all the genera and species oc- curring within our faunal limits. The Anthonomini of Europe have been made the subject of a monogra})h by Desbrochers des Loges (Monographic des Balaninidse et Anthonomidie d’Europe et de confines Mediterranees, 1867), which has, however, scarcely offered a suggestion that might have aided me in the study of our North American species. The genus Orchestes was similarly treated by Brisout (Monogr. Ann. Fr. 1865). Very recently a paper has been published on the species of Anthonomus inhabiting Great Britain ; the latter publication I have not seen. In taking a general comparative survey of the present tribe of Curculionidie, as presented by our own with that of the European fauna, one is struck with the few points of close similarity encoun- tered. Referring to Anthonomus proper, the European species, as far as I am able to judge by the not inconsiderable number repre- sented in my collection, present far greater uniformity, structurally as well as in general habitus, than our own. In all of them the funicle of the antennie consists of seven joints, and species entirely clothed with scales do not occur. The European genus Bradybatus Germ., in which the claws are connate at base, is not represented in our fauna. In defining the limits of the tribe, a modification of LeConte’s arrangement becomes necessary. Several new genera have been included, whose position is somewhat doubtful, and which, with equal j)ropriety, might have been placed in some other tribes of the Me- TRANS. AM. ENT. SOC. XVIII. (23) JULY, 1891. 178 AVILLIAM G. DIETZ, M. D. corrhyndiid series. One of these, Alycodes, whose affinity to the Erirrliini is well shown by the formation of tlie ventral segments, the covered pygidiiim and the sim])le claws, and by its toothed femora, would have to he placed after Dorytomus, hut the obliquelv truncated anterior thoracic opening, the prosternum short in front of tlie coxffi, the antennal formation, etc., have induced me to jilace it in the })resent tribe. Another aberrant genus, Euclyptus, resem- l)les Xoto/ovius basu/is Lee. in its general appearance, and also in the ventral formation ; the prosternum, however, is short in front of the coxffi, the j)ygidium freely exposed, and the appendiculate claws warrant its position here. Elleschus, placed by Lacordaire among the Tychiides, I have retained in the present tribe; the second, third and fourth ventral sutures are slightly bent backward at the sides; this character is also noticed in a few Anthonomi (A. elegam, jinii- perinu-s). Simple claws occur in a small number of species, dis- tributed among several genera. This abnormality in the present tribe is the final result of a gradual reduction in development, passing from the bifid claws of some Anthonomi (Anthonomorphus) to the very small, though distinct tooth of Chelonychus and a few others, to disappears altogether in Epimechus, Ephelops, etc. A remarkable character exists in the subcontiguous middle coxje of Magdalinops. As will be seen further on, considerable inq)ortance has been attached to the relative length of the ventral segments. The .sexes can generally be separated without much difficulty by keeping in view the following points : Ma/e. — Beak stouter, more coarsely sculptured and generally more o})aque ; anteniiie inserted nearer the aj)ex, or more coi-rectly sj)eak- ing, the beak as already pointed out by Jekel (Annales de la Soc. Entom. de France, 1864) is less prolonged beyond the insertion of the antennie, the distance of the latter from the base is about equal in both sexes. Female. — Beak more slender, less coarsely punctured and more shining ; anteniue more remotely inserted from the apex. The third and fourth ventral segments appear to be a trifle shorter in the males ; the fifth is generally longer and rounded in the female ; shorter, subtruncate, or eniargiuate in the male, permitting the py- gidium to become more or less visible from below. The latter is more freely exj)osed in the male, rarely entirely covered by the apex of the elytra, while frequently only partially exj)osed or entirely concealed in the female. NORTH AMERICAN COLEOPTERA. 179 The tibial armature, and especially the mucro of the posterior tibiie, is more slender and longer in the male than in the female. As is well known, all the members of the present tribe are phyto- phagous, and the greater number, no doubt, spermo])hagous. A few, like A. sycophanta, P. cratcegi, Coccotorus, etc., are said to breed in galls. I regret that I have nothing new to offer in the life-history of these insects. Family CURCULIONID.E. Tribe Anthonomini. Mandibles bi-emarglnate and three-toothed at tip; gular peduncle long ; oral organs small. Beak cylindrical, long and slender; more rarely moderately stout and shorter (Macrorhoptus, some Anthonomi). More or less curved in all, but nearly straight in Macrorhoptus and Cionistes. Scrobes commencing at a distance from the buccal opening (less remote in the subgenus Paranthonomus) ; straight or somewhat curved ; directed against the middle or lower segment of the eyes; more rarely (Mac- rorhoptus, Cionistes, Pseudanthonomus and Ephelops) oblique and directed beneath the eyes. Antenme variable, long and slender in the great majority ; in- serted at a distance from the apex ( less remote in Paranthonomus) ; subbasal in certain Orchestes (Alyctus Thoms.). Scape long and slender, rarely (Macrorhoptus, certain Orchestesj short and stout ; in- crassate at its distal extremity and generally impinging against the eye, except in Tachypterus and those genera having the scrobes oblique and directed beneath the eyes. Funicle live to seven jointed, glab- rous; first joint stout, generally elongate; following joints variable, each with a verticel of six to ten stiff or flexible hairs; rarely I Acalyptus and Euclyptus) entirely pubescent. Clava elongate oval or elliptic, acuminate, pubescent; closely or more loosely articulate (first joint strongly glabrous in Magdalinops, some Anthonomi and Neomastix), rarely very elongate and very loosely articulate (Ta- chypterus and in the subgenus Leptarthrus), or broadly oval and closely articulate (Neomastix). Eyes at least moderately large, roumled and remote from the pro- thorax ; rarely (subgenus Anthonomorphus) small and subrostral in their position ; widely separated above, and nearly flat or moderately convex in most; rarely (A. elegans, leucosticfus ; Leptarthrus, Or- 180 WILLIAM G. DIETZ. chedes) very prominent, and approximate upon the front; large, transver.sely oval and approximate beneath in ]\Iacrorhoptus. In a number of species the posterior margin of the eyes is more or less free and elevated, in consequence of which its surface is directed more anteriorly. Head more or less rounded or conical, not deeply immersed into the prothorax (except Cionistes). Prothorax wider than long (except A. brunnipennis) ; narrowed in front; anterior opening obliquely truncate (except Acalyptus). Very rarely (Macrorhoptus, subgenus Anthonomorphus and Tricho- baropsis) emarginate antero-inferiorly and giving a feeble appearance of postocular lobes ; base bi-emarginate, produced in front of the scutel ; latter small, oval or rounded, densely pubescent or scaly. Elytra variable, generally wider at the base than the prothorax ; striato-punctate (striae confluent at base in most Pseudanthononii). The outer margin shows the following variation: in those species having the elytra ample, that is, completely concealing the pygidium, the outer margin of one elytron forms a continuous horizontal line in its juxtaposition with the other and the outer stria unites with the sutural stria at an almost right angle. On the other hand, in those species in which the pygidium is freely exjiosed, the outer margin of each elytron ascends towards the apex, forming an angle in which the pygidium becomes more or less visible, and the outer and sutural strife unite at a more or less obtuse angle. In the text, the term dehiscent has frequently been used to denote the latter character, which varies greatly in extent, being most strongly marked in A. profimdus, elegans, etc., and scarcely noticeable in A. nebulosus, pe- ninsularis, etc. Prosternum short in front of eoxfe (long in Acalyptus, and mod- erately so in Anth. ipfipes and disjunctus). Anterior coxte contigu- ous, rather large and prominent ; middle coxje separated liy the mesosternum (subcontiguous in Magdalinops) ; the latter generally narrow, very rarely (subgenus Anthonomocyllus) wider than long, between the coxie. Metasternum moderately long (short in Antho- nomocyllus) ; side pieces narrowed posteriorly. Posterior coxfe widely separated (only moderately so in Magdalinops). Ventral segments variable in length ; subequal in Macrorhoptus, Tachypterus, Magdalinops, and some Anthonomi. First and second segments elongate (scarcely elongate, with the first segment short behind the coxie in Anthonomocyllus ; very strongly elongate in Ts’ORTH AMERICAN COLEOPTERA. 181 Anthonomopsis). Third and fourth segments shorter than the for- mer, rarely (Alycodes, Elleschus and Euclyptus) very short. The fifth segment, aside from sexual differences as noted before, attains its greatest length in iVlycodes, Elleschus, Euclyptus and a few species of Anthonomus. The sutures are straight and deep, except the first, which is less deeply impressed (almost obsolete in Anthonomopsis) ; the latter is (aii’ved in Elleschus, Anthonomopsis and Euclyptus. The pygidium varies in size ; it is oblique and concealed in both sexes in Alycodes, Macrorhoptus, JMagdalinoj)S, Tachypterus and Elleschus; more or less exposed, at least in the male in all the others. The more perpendicular its position, the more freely exposed it be- comes. It is indexed in some males, where it fits into the emargina- tion of the last ventral segment ; this is most notably the case in Coceotorus, to a less extent in Anthonomocyllus and Xeomastix. It is narrowly excavated in a longitudinal direction in the subgenus Paranthonomus. Legs never very stout (except Nanops) ; thighs more or less cla- \ ate and generally toothed. Tibire generally slender ; posterior of male curved in Anthonomocyllus and Cnemocyllus ; toothed inter- nally in A. elegans and Leptarthrus irroratns. The apical armature requires more than a passing notice. It consists either of a hook, unguiculum, arising from the apical articulating surface, curved in- ward at almost a right angle with the tibial axis, or else a mucro, a prolongation of the internal apical angle into a point, in the direc- tion of or approximating to the longitudinal axis of the tibia. Being morphologically distinct, I have found differences in the armature of sufficient importance to be made use of in the separation of genera. The anterior and middle tibiae are unguiculate, and the posterior mucronate in the majority of genera. All are unguiculate in Alycodes, Tachypterus, Magdalinops, Macrorhoptus, Chelonychus, Anthonomopsis, Elleschus and Nanops. Acalyptus has the anterior and middle tibiae unarmed, the posterior feebly mucronate, while in Euclyptus all the tibiae are unarmed, and in Xanthus the armature becomes very feebly developed. Tarsi variable, never very stout (except some species of Elleschus) ; frequently long and slender ; third joint bilobed, spongy or pubescent beneath, fourth joint generally of moderate length (short in Elles- chus, very long in several species of Cnemocyllus). Claws somewhat approximate and armed with a large tooth in the great majority ; 182 WILLIAM G. DIETZ, M. D. the tooth is either curved inward at the apex and approximate to, or else straight and parallel with the tooth of the other claw. The tooth is small and inconspicuous in a few Anthonomi and Nanops, and especially so in Chelonychus, where the claws are also bent back- ward. The claws are appendiculate, that is, armed with a broad tooth beneath in Elleschus, Euclyptus and Orchestes, and entirely simple and more widely divergent in Alycodes, E])imechus, Ephelops, Xan- thus and Acalyptus. The species of the present tribe are mostly small insects, a few almost minute; none in our fauna, at least, exceeding 6 mm., or .25 inch, in measurement.* The vestiture consists of pubescence or scales. In Anthonomoclneta the pubescence is intermixed with erect seta?. In conclusion of these introductory remarks, I desire to express my thanks to all who have kindly permitted the use of their material, especially Dr. G. H. Horn, Mr. E. A. Schwarz, Mr. H. Ulke, Mr. A. Balter, Mr. R. Rauterberg and Dr. John Hamilton. I am under great obligation to my friend.

Subgemis Anthonomus. I have hut little to add to the definition of the genus as here re- stricted, to what has been given in the table. The fifth ventral seg- ment of the male is hut rarely emarginate. The funicle is 6-jointed in but a small number of species. The present suhgenus contains by far the greatest number of spe- cies, which j)resent structural differences of considerable importance, and which I have made use of in subdividing the species into the following groups : Funicle seven-jointed. Upper surface pube.seeut (scales, if auy, are arranged in spots or lines, except A. concinnus) ; claws strongly toothed. Elytra conjointly rounded at the apex; pygidiuin of % very little exposed; pubescence dense, arranged in patterns on the elytra. nebulosus Group. Elytra not conjointly rounded at the apex ; pygidiuin, at least of the male, more fully exposed ; pubescence uniform, or condensed in spots or lines without distinct patterns. Anterior femora bidentate gularis Group. .interior femora unidentate. Third ventral segment longer than the fourth; fifth segment shorter, rarely as long as the fourth in the male. Pubescence of elytra uniform, rarely condensed in spots or lines, and without denuded patch or fascia. PI. vi, fig. I4...suturalis Group. Elytra with spots or lines of condensed pubescence, enclosing a denuded patch or fascia. PI. vi, fig. 15 sig-natus Group.

Upper and lower surface pubescent; claws armed with a small, inconspicuous tooth juniperinus Group. Upper and lower surface clothed with scales; tarsi long squamosus Group. Funicle six-jointed. Claws armed with a large, distinct tooth subfasciatus Group. Claws armed with a short basal tooth ung-ularis Group. nebulosus Group. I have nothing fuither to add to the description of this group, as given in the synopsis, except that the tooth of the claws is rather NORTH AMERICAN COLEOPTERA. 203 shorter and more obtuse than in the other species with 7-jointed funicle, in this respect resembling rather ^4. pyri, ulmi, ornatus, etc., of Europe. In fact, the two species belonging here, one of which is introduced from Europe, are more characteristic of the fauna of that continent than our own. The two species are readily distinguished as follows: More robust, anterior thighs bideutate, pubescence more squamiform. iiebiilo^iiiis Lee.

Abdomen less densely and more coarsely pubescent, pygidium very little ( '^ ) or not expo.sed (f). Legs moderately stout, thighs clavate, anterior bidentate, internal tooth lofig, outer tooth small, triangular and connected with the former at the base. Tibiae rather shorter and stouter than usual ; anterior pair curved near the base, pos- terior near the apex : armature strong.

Legs more slender, femora feebly clavate, unidentate, anterior femoral tooth very large, acutely triangular, external margin perpendicular; tibim and tarsi as in nebulosus. Long. 4 mm. ; .16 inch. Hab. — Ohio. A female specimen of this common European species was received some years ago among specimens of nebuloms, to which it hears a superficial resemblance. The less robust form and large, single tooth of the anterior thighs, will readily distinguish the present species. It is with some hesitancy that I introduce this species as occurring in our fauna, based, as it is, on a unique specimen. g’ularis Group. The species belonging to this group have the anterior thighs bi- dentate, the i)ygidium rather freely exposed, and the j)ubescence coarse or sparse, without any attemi)t at forming distinct j)atterns. NORTH AMPHilCAN COLEOPTERA. 205 The second joint of fiinicle is longer than the third. Legs and tarsi slender (except grandis), claws armed with a long, slender tooth.

Loug. 5 — 5.5 mm. ; .20 — .22 inch. Hab. — Mexico, Texas. Whether the introduction of this species into our faunal limits is permanent or not, future observations must decide. Three specimens are before me, two in the collection of Dr. Horn,* labeled Mexico, and a sitecimen in INIr. Schwarz’s collection from Texas. Thev tallv well with the description given by Bohemann, though the descriptive expression in reference to the elytra — “ thorace plus triplo longiore” *■ Sent me with the information that they injured the cotton plant (G.

The third and fourth ventral segments are shorter than in the other members of this group. .4. Lee. — Oblonpi-elliptic, pitchy black, .shining, finely and sparsely clothed above with whitish pubescence. Beak shining, finely punctured; three feebly elevated lines extending from the base to about the insertion of the au- tennse, the median line extending upon the front; scrobes deep, straight. An- teniife slender, second joint of funicle longer than the third ; scape and first joint of funicle bright rnfons, succeeding joints fuscous, verticels consisting of about 7-8 long, flexible hairs. Head short, conical ; frontal puncture very small or obsolete; occiput very finely and remotely punctured, front finely rugose. Eyes moderately convex, posteri»>r margin free. Prothorax scarcely wider than long; sides nearly straight behind, strongly rounded and narrowed anteriorly, not constricted at apex; posterior angles not rounded and base not bisinuate ; surface densely and rather coarsely punctured on the sides, less so on the disc ; pubescence somewhat condensed near the posterior angles and along the median line. Elytra oblong, a little wider at the base than the prothorax, feebly rounded on the sides and separately rounded at tip, almost twice as long as wide; striae finely impressed, punctures small, elongate, and not closely approximate on the disc, a little coarser and more closely placed on the sides; interspaces wide, flat finely punctulate; scutellum densely clothed w'ith yellowish pubescence; under- side of head, thorax, and sides of abdomen, densely clothed with pale, yellowish squamiform pubescence.

Long. 3 — 3.5 mm.; .12 — .14 inch. Hub. — Virginia, West Virginia, ^Maryland, Michigan. Each elytron has a fnscons reflection along its disc. This species could only be confounded with the following, from which it is dis- tinguished by the characters given in the table. .4. Virgo n. sp. Plate vi, fig. 13. — Eesembles gularix in form atid pubescence. It differs as follow's : Beak more densely punctured, less shining; median ele- vated line, scarcely attaining the base. Head opaque, densely and finely punc- tured, front with an imjjressed line. Prothorax rnfo-piceous. Elytra bright ferruginous, periscutellar space and along the suture dark piceons ; anterior tibite fringed with hair along the inner margin ; anterior tibiae of male curved inward near the apex, and the internal angle produced in form of a broad hook. Legs and abdomen along the middle ferruginous. Long. 2.5 — 3.4 mm. ; .10 — .15 inch. Hub.— Cohh’s Island, Va. Coll. E. A. Schwarz. Two males and one female. The female has the anterior tibise simple; neither curved nor produced at the apex ; one male is much smaller, and has the elytra entirely piceons and the legs partly so. NORTH AMERICAN COLEOPTERA. 207 A. riifipeiiiiiN Lee. — Of the same general liahitus as gularis, but smaller, and the pubescence a little more pronounced. It differs in the following char- acters: Piceous, elytra ferruginous. Beak shorter and stouter, opaque; striolate with several rows of remote punctures, lateral elevated line more prominent, median not extending u])on the front. Anteunse pale rufous, club dusky, second joint of funicle elongate. Eyes convex, but not free behind. Prothorax scarcely one-half wider than long. Elytra semi-opaque, strife and punctures more strongly impressed ; interspaces slightly convex, finely rugose, each with several irregular rows of punctures ; scutellar space and along the suture darker; the pubescence on the under surface is white and as dense as in gularis ; the legs are a trifle stouter. Long. 2.2 —3 mm. ; .09 — .12 inch. This species varies somewhat in size and coloration, some speci- mens are entirely rufous; the pubescence, also, is more pronounced in some than in others. LeConte’s description: “thorax a little longer than wide,” does not correspond with any specimens before me, nor does the statement in his synoptic table of species — that the anterior thighs are uniden- tate. The smaller, outer cusp is well marked in all but a single specimen, in which it is nearly obsolete. Hab. — Pennsylvania (LeConte), Illinois, Texas, Florida. suturalis Group. The species belonging to this group have the anterior thighs uni- dentate. The ventral segments decreasing in length from the second, the third segment being always longer than the fourth, and this lon- ger than the fifth, at least in the male, except corvulus, where the fifth is scarcely shorter than the fourth segment. In general, the species are rather sparsely pubescent, except suhguttatus, all the femora armed with a single tooth (hind pair mutic in melancholwm), although the tooth of the posterior pair becomes nearly obsolete in specimens of siibguttatus and mondus. The tarsi are more slender than in the next group, and the first joint longer than the second; the elytra are without a denuded fascia ; lines and spots of pubes- cence do not occur, excejit in suhguUatus, more rarely in flavicortds. The species are closely related, and while it is not difficult to rec- ognize typical specimens, aberrant forms occur whose exact position it may not be always easy to determine. I have arranged the species as follows : Entirely rufo-testaceous or ferruginous, underside of thorax generally darker. Elytra finely striate, punctures small, interstices flat, wide; antennae slender. Elytral interspaces rugose, prothorax not constricted at apex ; larger species. Bolfei’i. Elytral interspaces smooth, prothorax strongly constricted behind the ante- rior margin riibellus. 208 WILLIAM G. DIETZ, M. I).

Eiytra finely striato-punctate, shining; anlennie testaceous. Prothorax conical, strongly narrowed from base to apex, sides feebl.y rounded; surface finely and densely punctured., inelaiicliolicus. Prothorax transverse, sides strongly rounded, coarsely but not densely punctured flavicoriiis. Elytra finely striate, punctures moderate; interspaces flat, rugose aud with- out lustre nioriilns. Elytral stripe deeply impressed ; punctures large, distant ; interspaces convex, shining corviiliis. Pubescence coarse, conspicuous, forming spots or lines on the elytra. .4 Kolteri n. sp. — Oblong, ferruginous, thiuly clothed with fine, whitish pubescence. Beak slender, curved, subopaque, finely pubescent and punctured, substriate at the base with a finely elevated, smooth median line.

Head convex, punctured ; punc- tures large, remote and superficial ; frontal puncture small. Eyes convex, poste- rior margin somewhat free. Prothorax more than one-half wider than long; sides feebly rounded from base to apex, latter scarcely constricted and about two-thirds as wide as the base, which is only feebly bisinuate; surface densely and rather finely punctured. Elytra oblong, about one-third wider at the base than the prothorax, somewhat shining ; sides parallel for two-thirds their length, rather suddenly narrowed to and separately rounded at the apex; strise finely impressed ; punctures small, approximate, a trifle larger toward the base; inter- spaces flat finely rugulose, a small, subhumeral tubercle on tbe ninth interspace, visible from above; scutel densely pubescent, under surface with a few remote punctures; meso- and rnetathorax darker, and especially on the sides densely clothed w'ith .sqiiamiform pubescence. Abdomen sparsely pubescent. Legs slender, femora moderately clavate, all armed with an acute tooth. Tibiae feebly bisinuate internally ; tar.si slender. Long. .3 — 3.2 mm.; .12 — .13 inch.

Elytra subovate, almost one-third wider at the base than the prothorax, slightly widened posteriorly; sides broadly rounded to the apex, which is scarcely dehiscent aud covers the pygidium almost completely ; strife moderately fine, becoming deeper and wider toward the base and sides; punctures moder- ately large, round, and not closely approximate; interspaces feebly convex' smooth and scarcely pubescent ; underside with a few remote i)unctures. other wise as in BoUeri, but the pubescence is less marked, and the pygidium almost completely concealed by the elytra. Legs and tarsi as in that species. Long- 2.2 mm. ; .09 inch. Hah. — Lake Superior. A unique female in my collection. It might be confounded with the preceding species, its nearest ally, but differs especially in size and form of prothorax. From eonfums it is distinguished by the much less pronounced elytral sculjtture and the intersiaices being smooth. COiiriiSii<$ n. sp. — Similar in form to A. Bolteri ; rufo-testaceous, pubes- cence coarser and more conspicuous. Beak a little stouter and less curved ; me- dian elevated line very feeble, or almost obsolete; more densely and coarsely punctured. Antennge stouter, second joint of funicle less elongate, but always longer than the third. Eyes scarcely convex, posterior margin uot free. Head a trifle more coarsely punctured. Prothorax constricted at the apex, bisinnate at the base. Elytra coarsely striato-puuctate, punctures large and round, almost or quite as wide as the inter.siiaces near the base ; pubescence coarser and longer ; undeiside, legs and tarsi as in Bolteri. Long. 2. .3— 3 mm. ; .09 — .12 inch. Hab. — California, Montana, Wyoming. The three [treceding specie.s are very closely related, but more ex- tensive series are necessary, to prove them as mere variations of one species. Two specimens in Dr. Horn’s collection, from Montana, which I refer to the present species, show a decided similarity to Bolteri in the less coarsely punctured, elytral strim, more convex eyes, le.ss conspicuous pubescence and larger size. syeaque, feebly striate and punctured. Antenute, head and eyes, as in that species. Prothorax transverse, more stroTigly rounded on the sides behind, narrowed in front, constricted and transversely impressed behind the anterior margin; surface more densely and finely punctured, base bisinuate. Elytra! strife not strongly impressed; punctures small, not verj’ close; inter- stices flat, more shining and very finely rugose; scutellum clothed with white pubescence ; under surface as in that species, but the pubescence is a little more dense and squamiform ; the tibite are a little stouter, the tarsi longer, and the claws larger; the tooth of the latter is also a little larger. Long. 2.7— 3 mm. ; .11 — .12 inch. Hub. — Eastern and Western States. The red apical blotch varies greatly in extent, leaving always, however, the suture and scutellar space black. Larger sized speci- mens with the elytra almost entirely red, may be confounded with A. virgo, from which the present species differs by its nnidentate an- terior femora, more strongly elavate thighs and smooth rostral carina. Fi-om sycophanta it is to be distinguished, aside from coloration, by the sides of the ])rothorax being more strongly rounded and the apical constriction, the punctures also, are less coarse and less dense, and the elytra more shining. A specimen in Dr. Horn’s collection from Iowa, while evidently belonging to the present sjiecies, has the ])rothorax quite coarsely, though very closely, punctured. The elytra are entirely ferruginous, with a triangular basal space dusky.

A. melsiiiclioliciis n. sp. — Elongate-oval, black, with scarcely any lustre, and clothed with a fine, squamifonn pubescence, which is s])arse above and more dense on the under surface. Beak rather stout, coarsely punctured, opaque; median carina almost reaching to the apex ; scrobes scarcely attaining the eye. Anteniife rufo-test;iceous, not very slender; second joint of fnnicle longer than the third, joints 3-8 transversely rounded ; clava elongate, dusky. Eyes convex, more widely separated above than usual. Head convex, rat her coarsely jiunc- tured, with a well marked frontal fovea, and, like the beak, glabrous, excejit a few scattered scales.

J[ab. — Southern States (Patiii ?). A specimen in my collection, taken in this neighborhood (Hazleton, I’a.), measures scarcely 2.5 mm., but does not differ otherwise. Two specimens from Texas in Mr. Hike’s collection are a little less robust, with tw'o interrujjted lines of condensed pubescence on the elytra, thereby forming some similarity to subguttahis. From nigriuus, witii which the present species might be confounded, it is to be distin- guished by the less coarsely and less densely |)unctured prothorax, testaceous antennie and less slender legs. A. inoriiliis Lee. — Black, or piceou.s, robu.st and convex; pubescence fiue, sparse, a trifie more dense on the under surface.

Elytra about one-third and rather suddenly wider at base than the jirothorax and less than one-half longer than wide ; the sides, seen from above, appear slightly emarginate behind the humerus, due to a feeble bulging outward of the ninth and tenth interspaces, rather suddenly nai-rowed to the apex, which is separately rounded and widely dehiscent, leaving the f)ygidiuin freely exposed ; striae fine, punctures moderately large and approximate; inter- spaces flat, suhopaque and rather strongly rugose; under surface ]iunctulate. Legs nut very slender, thighs moderately clavate, all armed with a small, acute tootk; tibiae slightly widened toward the apex, anterior and middle scarcely biemarginate, posterior straight; tarsi moderately slender, tooth of claw long and slender. Long. 2.6 — 2.8 mm.; .10— .11 inch. NORTH AMERICAN COLEOPTERA. 213 Hah. — California. Only two female specimens in Dr. Horn’s collection are before me. Bears a striking resemblance to Eprinechm viwiicus, described further on, from which, indeed, it cannot be distinguished, except by the toothed claws. Since writing the above I have received a specimen from Dr. Horn, which has entirely the coloration of a typical A. snturalls, the elytra being bright rufous with the exception of a triangular basal space ; it is easily recognized, however, by the form of the jirothorax and the le.ss shining elytra. A. corvnlus Lee. — Rather robust, oval, black shining: pubescence rather long and coar.se, but sparse and easily removed. Beak moderately slender, punc- tured with well-marked median carina ; scrobes curved, somewhat ap])roximate beneath and directed against the lower angles of the eyes. Anteniife stout, rufo- piceous; scape paler, second joint of fuuicle scarcely longer than the third, following joints gradually wider, verticels consisting of stiff, bristle-like hairs. Eyes feebly convex and slightly free behind. Head convex, occiput impunc- tured, front with a few punctures and a well-marked fovea. Prothorax trans- verse, more than one-half wider than long, strongly rounded on the sides and gradually narrowed to apex, which is feebly constricted ; base scarcely hisinuate, surface coarsely, hut not densely punctured. Elytra about one-fourth wider at the base than the prothorax ; humeri rounded ; sides a little widened to behind the middle, separately rounded at tip, leaving the pygidium freely exposed ; striae deejdy impressed, wide: punctures large, not closely approximate : interspaces convex, smooth, with small, remote punctures: scutellum white jmbescent: underside remotely punctured, pubescence more dense. Legs .slender, thighs feebly clavate, all armed with a small, acute tooth : tibiae almost straight, and at the apex, like the tarsi, brownish. Long. 1.5 — 2.2 mm. : .06 — .09 inch. Hah. — Pennsylvania, Massachusetts, District of Columbia, Illinois, W isconsin, Michigan, Texas, Arizona. Easily recognized by its small size, shining black color, coarsely punctured prothorax and s])arse pubescence. The pubescence is easily rubbed off, giving the insect a still more shining appearance, and on sujierficial examination, might give rise to confusion. Speci- mens are before me of a brown color, probably due to their being immature. A. sill>$;iittatiis u. sp. — Elongate-oval, piceous, more slender, but other- wise closely allied to Jlavicornis, from which it differs in the following charac- ters: Pubescence coarse, dense and white. Beak more slender and shining, finely and less closely punctured : median carina more distinct, shining, and ex- tending to the frontal puncture. Head not concentrically rugulose, second joint of funicle scarcely longer than the third.

Hub. — Florida, District of Columbia. A specimen in Mr. Dike’s collection, from District of Columbia, differs from the typical form by the pubescence being jiale yellowish, sparser and less coarse. This species might jiossibly be referred to the signatus group, with which, however, it has no close relationshiji ; the first and second ventral segments are relatively shorter, and there is no denuded elytral fascia. Dr. LeConte indicated this species under A. scutella- tus Gyll. ( Proc. Amer. Phil. Soc. vol. xv, p. Uh)), hut failed to de- •scrihe it. sig-natus Group. This group contains species of rather small size, and presenting a similarity of habitus which makes them easy of recognition. They agree with those of the preceding group in the abdominal formation; the first and second ventral segments, however, are genei’ally longer and nearlv ecjual in length, the gradual decrease in length commen- cing with the third segment, instead of the second, as in that grouii. The elvtra have a post-median denuded patch or fascia, surrounded, in the fresh state at least, by spots or lines of pubescence. They difier very little in sculpture, and are to be distinguished rather by a general assenddage of characters and habitus. The first two tarsal j(dnts are equal, or nearly so. The following table, supplemented by the Sjiecific description, will enable the student to identify his species: Elytral interspaces equal, or nearly so. Front foveate. Larger ami more robust, second joint of funicle distinctly longer than the third; prothorax strongly rounded on the .sides. Frontal fovea small, punctiform ; pubescence fine, inconspicuous.

Plate vi, fig. 15. —Robust, oval, ]iiceons ; elytra red, de- nuded fascia and scutellar space darker, thinly clothed with whitish pubescence. Beak moderately slender, feebly curved, subopaque and rather densely striato- punctate; median carina, smooth, distinct. Antennae testaceous, club darker, funicle rather stout, outer joints distinctly wider, second joint distinctly longer than the third, but not slender; joints 3-7 transversely rounded. Eyes moder- ately convex, free behind. Head convex, occiput somewhat shining, front with a few remote punctures, finely and indistinctly rugulo.se, frontal puncture dis- tinct. Prothorax wider than long, moderately narrowed in front; sides not strongly rounded, feebly constricted at the apex and transversely impressed behind the anterior margin; surface rather coarsely and densely punctured, pubescence condensed along the median line. Elytra less than one-fourth wider at the base than the prothorax and about one-half longer than wide, a little widened to behind the middle; sides feebly rounded ; strife impressed, punctures moderately large, close set and becoming smaller towards the lateral margin ; inter.spaces slightly convex, shining with an irregular row of fine punctures; the denuded fascia extends from the side to the third interspace, another de- nuded spot on the second interspace ; scutellar space and along the suture darker ; scutellnm and iutra-humeral spot densely pubescent. Thorax underneath more densely clothed with white, squamiform pubescence. Abdomen sparsely i>ubes- cent, segments transversely strigose, first and second segments rather long. Legs slender, femora feebly clavate, piceous, all armed with a sharp, well-marked tooth ; tibife paler, anterior feebly bisinuate, middle and posterior nearly straight ; tarsi pale, first joint elongate.

Why Prof Riley should con- sider this species identical with sir/natus (Agric.

The third and fourth ventral .segments are of e(jual width, and the fifth distinctly longer than either ; the pygidium is freely visible from below. This species, although very distinct, is closely allied to fiavicornis, nigrinns and albopiloms. It resembles fiavicornis so closely that, if viewed from above, it cannot be distinguished, except by its somewhat greater size ; the abdominal formation, however, is strikingly different, the beak, legs and tarsi much more slender; the first j'oint of the anterior tarsi twice as long as the second, while equal in fiavicornis. From the next species it differs by its being more robust, the beak more slender, thorax less coarsely punctured, the femoral tooth spini- form, the anterior and middle tibim curved near the aj)ex, and the more slender tarsi with the first joint nearly twice the length of the .second.

Long. 3 mm.; .12 inch. Hab. — Virginia. A single 9 in my collection found among a lot of loose material sent me years ago hy Mr. H. Ulke, of Washington, and labeled “ Virginia.” This species is an exact reproduction of A. ungularis in form, color and pubescence, but for the 7-jointed funicle, absence of elytral fascia and very slender tooth of claw, it could not possibly be dis- tinguished. The fifth ventral segment is longer than the preceding.

The anterior coxte are more prominent than usual, and the ventral sutures curved slightly backward at the sides ; the beak, also, in re- pose seems to be deflected further backward than is usual among other members of this tribe. 228 WILLIAM G. DIETZ, M. I). This species, at once recognized by its pale testaceous color and dark elytral spot, has a remarkable similarity to Nanophyes trans- verms Aube of Southern Europe, and which, according to Desbro- (‘liers,* was described by Chevrolat as Anthonomus juniperi. squamosus Group. Contains all those species with 7-jointed funicle, in which both the upper and under surface are ])redominantly clothed with scales. The scaly vestiture, while dense in most of the species, is sparse and intermixed with a fine pubescence in some. The scales also vary from almost round to very elongate, piliform. The ventral segments are less unequal than in the majority of the pubescent species. Some of the vittate forms shoAV great similarity to the species of the sub- genus Cnemocyllus, from which they differ merely by the hind tibise of the male not being dissimilar from those of the female. The species may be tabulated as follows : Stout species ; all the femora armed with a tooth. Anterior thoracic opening very oblique, prosternum short in front of the coxai. Elytra without transverse, partly denuded fascia. Beak and antenufe slender; legs reddish, or rufo-piceous. Larger; beak long and very slender; first and second joint of funicle elongate. Not densely clothed with scales, which are more or less piliform ; color pitchy-black, legs rufo-piceous ater. Densely clothed with oval scales, reddish t.

Closely allied to squamosus, from which, indeed, it ditiers but little structurally, excejit in the form and density of the scales. Comjiarison will show at once that it should not be placed among the pubescent species. .A. $«qiiainosns Lee. — Oval, reddish brown to piceous, densely covered with grayish white, or pale yellowish, oval scales; otherwise, like the preceding spe- cies, from which it differs, aside from coloration, form and density of scales, as follows: Beak reddish brown, more shining, less punctured and scarcely striate.

Might easily be mistaken ^ovhirtm; in fact, the descriptive phrase, as given by LeConte of that species, “ densely clothed with coarse, scarcely squamiform, ochreous jtubescence,” a|)plies far better to the sjtecies under consideration ; it is, however, less elongate, the eyes slightly encroaching u|)on the front, the prothorax distinctly wider than long, the thighs more strongly clavate, and both anterior and middle armed with a tooth. The peculiar curved projection of the terminal hook of the anterior and middle tibise I do not remember of having observed in any other sj)ecies. One of the specimens has a strongly marked, oblique impression each side of the jirothorax. The unusual occurrence of this kind of sculpture in the present tribe is no doubt due to some disturliance in the earlier stages. A. |>aii|>ei'culii$« Lee.

Under this subgeneric name I have included all those species which have the posterior tibite dissimilar in the two sexes, those of the male being more or less curved, while in the female they are straight, or nearly so. This curvature varies greatly, being most marked in ornatulus and figuratus, and least in Ugatns. The fifth ventral segment is more or less elongate, except in sabvittatus, or- natulus and jiguratus, and very long in inermis. The tarsi are never short and broad, but are very long and slender in a few sj)ecies. The tooth of claw varies considerably in development. The form varies from oval to elongate, and the integument is clothed with scales, which, in most of the species, form lines or vittae after a com- mon pattern, as follows: A pale line on the fourth interspace com- mencing about the middle and variable in extent, another vitta on the sixth interspace commencing at the base and extending to about the middle; in addition to these there is in some a darker patch or fascia on the sides behind the middle. The prothorax is generally vittate ; the funicle of the antemue is either 6- or 7-jointed. The species occur in the Western and Southern States, are closely related, and require great care to be distinguished. The following table, sujiplemeuted by the descri|)tions and figures given, will, how- ever, enable the student to positively identity them. Funicle 7-jointed.

Dr. Horn, who, in this instance also, has kindly made the com- parison with the type in the LeConte collection at Cambridge, has found the funicle to consist of only six joints and not seven, as erro- neously stated by LeConte, and which had led me to doubt the identity of the present species with the one described by LeConte. This species is very closely related to the following, with which it has heretofore been confounded in collections. A specimen from Jacksonville, Fla., in Mr. Schwarz’s collection, I refer, with some doubt, to the present species; it has the beak a little shorter and stouter, the second joint of funicle a little shorter than the third, outer joints wider ; the elytra a little wider at the base and not wider posteriorly, sides feebly rounded, punctures close set and somewhat transverse, interspaces more roughened, and the anterior femora more strongly clavate ; it is entirely denuded of scales.

One of Dr. Horn’s specimens agrees in all particulars (except sexual differences) with mine, while the other has the denuded fascia of less extent and the interspaces not denuded near the base. I have made careful comparison with well authenticated specimens of this species from Europe, and can discover no difference, except that a small denuded spot each side of the thorax is wanting in our specimens, but as this also occurs in one of my European specimens, it is probably of but subordinate value. E. ppisitus Say. Plate vii, figs 35c, 35d. — Elongate, ferruginous, mottled with pale yellowish and fawn-colored pubescence. Beak punctured. Prothorax rather finely and not densely punctured. Elytral strife with large, closely pLaced punctures; a large scutellar spot and another somewhat rhomboidal space behind the middle connected along the suture, of darker color. A trans- verse fascia of grayish pubescence immediately behind the posterior dark space; underside punctured ; the claws are slender and armed beneath with a large rectangular tooth at the base. Long. 2 — 3.3 mm. ; .08 — .13 inch. Hab. — Atlantic States; Michigan, Georgia, Kansas, New iMexico, Oregon, California. A very variable species. The dark elytral spaces are almost ob- solete in some specimens. Mr. Thos. Casey very kindly has sent me a typical specimen of his E. callforuicus. It is entirely pitchy-black, resembling in this respect rather bipunetatus ; legs a trifle paler. The beak is less punctured, shining, and the second joint of the funicle is longer than the third. In all other respects it agrees with ephippiatus, from which it does not appear specifically distinct, but forms a marked variety. E. n. sp. Plate vii, fig. 35d. — Elongate elliptic, femigiuous. not very densely clothed with whitish, squamiform pubescence. Beak rather slender and moderately long, punctured and somewhat shining; substriate and rather densely scaly from base to about the middle. Antennse slender; first joint of funicle long and slender, second a little longer than the third, outer joints hut little wider. Eyes as usual. Head punctured, occiput sparsely pubescent, densely squamous between the eyes. Prothorax wider than long, broadly rounded on the sides and very little wider at ba.se than at the apex. (34) TKANS. AM.

Legs rather slender, thighs feebly clavate, anterior armed with a small acute tooth, which is represented on the middle and hind pair by an acute angle, less marked on the hind femur; tarsi less robust, fourth joint extending considerably beyond the third ; claws armed beneath with a short obtuse tooth. Long. 2.8-- 3 mm. ; .11 — .12 inch. Hah. — Arizona, Kentucky. Two specimens, male and female, in Dr. klorn’s collection. A very distinct species and unmistakable members of the present genus. The rather slender beak and toothed femora are anomalous. ORC'IIEXTEN 111. The eyes clo.sely approximate above and the saltatorial })o.sterior femora make the recognition of the species of this genus an easy matter. "J'he beak, variable in length and thickness, lies between the anterior legs during repose : the scrobes commencing about the middle or even near the base; scape of anteniue not long ; funicle 6- or 7-jointed. The prothorax is relatively small. The elytra oval or elongate-oval, wider than the prothorax, with the humeri rounded. In reviewing the species I shall give only sufficient descriptive matter which, in connection with the synoptic table, will enable the student to identify his material. To the species heretofore known I have to add one new species. They may be tabulated as follows : Funicle of autennse 7-jointed. Elytra with patterns of pale pubescence. An anterior and posterior transverse baud, always con.s]iicuous. Anterior fascia wide, legs partly rufous epliippiaf US. .\nterior fascia narrower; legs entirely black ssilicis. A faint subbasal, transverse band only iiigor. Elytra unicolorou.s, black. Hind angles of jtrothorax rounded or rectangular, elytra without lateral spine parvioollis. Hind angles of prothorax acute; elytra with a subhnmeral spine. arinatiis. Funicle 6-jointed. Hind femora strongly thickened. Pubescence long and coarse, brownish pul»t*i*ulus. Pubescence fine, sparse and whitish. Black, thoracic jiunctures large, irregular; elytral interspaces coarsely rugose can us. NORTH AIVIKRICAN COLEOPTPHiA. 267 Black, thoracic punctures moderate, round ; elytra! intersj)aces almost smooth, shining pallieoriiis. Black, elytra and abdomen red Itefiileti. Hind femora scarcely thickened. Legs rufous riifipes. Legs piceous Var. iiiiiiiitiis. O. epliippiatiis Say. — Robust, oval, piceous; beak, atitennje and legs ru- fous. Prothorax small, rufo-piceous, not densely clothed with whitish pubes- cence. Elytra oval, much wider than the prothorax ; anterior two-hfths and a transverse post-median fascia rufous, or rufo-piceous and densely clothed with white pubescence and connected by a line on the second interspace ; femora, especially the posterior, wholly or in part piceous. Long. 2.5 — 3 mm.; .10 — .12 inch. Hab. — Pennsylvania, Iowa, Illinois, California, Wisconsin. Allied to 0. rujUarsis Germ, of Europe. O. saliciN Linn. — Similar to the preceding, but smaller and less robust Black, antennse and tarsi rufous; anterior elytral fascia narrower than in ephip- piatus, about one-third from the base, irregular, prolonged along the sutural in- terspace to the scutellum in front and extended along the second interspace posteriorly, but not connected with the posterior transverse hand which is nar- row and angulated. Long. 2.5 mm.; .10 inch. Hab. — California, Wisconsin. This is 0. subhirtus Horn. Careful comparison of Dr. Horn’s types with specimens of the European species in my cabinet leave no doubt of their identity. O. iiiger Horn. — Rather robust, subovate ; black, anteniife piceous, clothed with short pubescence, which is black on the upper and whitish on the under surface; scutellum densely white pubescent; an inconspicuous, transverse fascia about one-third from the base and consisting of sparse white pubescence. Long. 2.8 mm. ; .11 inch. Hab. — Illinois, Michigan, Pennsylvania. The white scutellum is in striking contrast with the rest of the su rface. O. pai'vic'ollis Lee. — Entirely black, oblong-oval with scarcely any lustre. Prothorax coarsely and rather densely punctured ; hind angles subrectangular, somewhat rounded. Elytral interspaces very rough. Long. 2.8 — 3 mm. ; .11 — 12 inch. Hub. — California, Nevada, Colorado. Distinguished from the three preceding species by the absence of elytral markings and from the following by its coarse sculpture, rounded posterior angles of thorax and the ninth elytral interspace not produced in a sjiine. 268 WILLIAM G. DIETZ, M. D. O. 11. sp. Plate vii, fig. 36. — Suhovate, robust, very convex, black and shining; very sparsely clothed with short, pale, suberect puliescence.

Antennae entirely pale testaceous, very slender ; scape shoi t, funicle 7-jointed. first joint long, second and third elongate, subequal, joints 4-7 shorter, rounded : clava elongate. Prothorax wider than long, and nearly twice as wide at base than at apex, sides oblique, nearly straight, feebly constricted at tip, hind angles acute, punctures moderately large and rather remote, each bearing a short whitish hair. Elytra broadly oval, very convex, not much wider at base than the prothorax ; humeri prominent, callous and lounded ; striae rather fine, punc- tures small and not closely approximate; interspaces slightly convex, smooth and shining, each with a row of fine, remote punctures bearing a short, hair: the ninth interspace near the base is produced in the form of a short, acute spine directed forward ; under surface a little more densely and coarsely pubescent ; hind femora scarcely incrassate; tarsi pale rufous. Long. 2.3 mm. ; .09 inch. Hab. — Allegheny, Pa. A single female specimen. Collected and kindly given me hy Dr. Hamilton. Very ditferent from any other Orchestes known to me and re- markable for its very convex form, shining surface, acute posterior thoracic angle, and the acute spine of the ninth intersjtace. O. puberiiliis Boh. — Elongate oval, black, anteniiie and legs testaceous, densely clothed with long, coarse, gray or yellowish gray pubescence; funicle 6- jointed; scutellum clothed with white pubescence. Elytra regularly oval, hu- meri rounded, not at all prominent. Long. 3.2—4 mm.; .12 — .16 inch. Hab. — California. Easily known by its coarse, yellowish pubescence. O. caiiti«« Horn. — Similar in form to the preceditig species, hut the humeri are more prominent. Black, autemife rufo-piceous ; t>'Jhescence short, sparse, whitish. Prothorax punctured, punctures rather crowded and irregular. Elytral interspaces rugulose. roughened with some lustre. Long. 2.8 — 3.2 mm. ; .11 — 13 inch. Hab. — Michigan, Colorado. Re.sembles 0. stigma Germ, of Eurojte, but the pubescence is white or yellowish, and the elytral strite are less deejtly impressed. O. pallicoi’iiis Say. — Similar to canus, but a trifle smaller, with the humeri still more prominent. Black, antennae and tarsi reddish. Prothorax less densely punct\ired, punctures less irregular; the elytral interspaces are nearly smooth and more shining. Long 3 mm. ; .12 inch.

NORTH AMERICAN COLEOPTERA. 269 O. riifipeis Lee. — Elliptic, smaller and less robust than any of the preceding species. Black, thinly pubescent: antennae aud legs rufous: hind femora feebly incrassate, more or less piceous. Long. 2 mm. : .08 inch. Closely allied to the European 0. foliorum Miiller, from which it appears to differ by the prothorax being a little more transverse and not rounded in front. O. minutus Horn is a variety of the above with the legs entirely piceons. It occurs in California and Colorado. XA\TIIUS gen . nov.

DIETZ, M. D. The type of this genus is a small testaceous insect without close relationship in any direction, except, perhaps, Acalyptus, with which it agrees in the somewhat flattened thorax, unarmed tibioe and the formation of the funicle. It agrees with Alycodes and Elleschus in the abdominal formation and appendiculate claws, but the fifth ven- tral segment is very long, and it is very different in other respects.

NORTH AMERICAN COLEOPTERA. 277 The species of .4GRIL.ITS of Boreal America. - BY GEORGE H. HORN, M.D. The first attempt at a comparative study of our species was made by Dr. LeConte in his “Revision of the Buprestidie of the United States (Trans. Amer. Philos. Soc. xi, 1859),” in which thirty-two species wei’e recognized and eight previously described enumerated as unknown. In this essay we find an important use of the form of the claws as the basis of a primary division of the genus in groups. Singularly the study of the claws was carried no further, owing probably to the small material which furnished the basis of the work. It is also to be regretted that but little attention was paid to the sexual characters, and, as if by accident, only an occasional allusion is made to the form of the prosternal lobe. Of the thirty- two species described, twelve were represented by single examples, and of the remaining twenty nearly half were represented by not more than two. While this condition rendered the study at the time easy and satisfactory, the further accumulation of material makes it absolutely necessary to refer to the types for determination. In 1873 (Proc. Acad. Nat. Sci. Phil.), Mr. G. R. Crotch attempted a brief review of our species, which is notable for the insufficiency of his comments in one portion of the paper and the numerous inac- curacies throughout, especially in the analytical table. The value of the Carina of the pygidium was first recognized in his paper, and some attempt made to use the sexual characters as a means of sepa- rating the species. The species of the regions to the south of our limits have been studied b}^ Mr. Waterhuuse (Biol. Cent. Amer. vol. ii, pt. 1 ) with fairly good results, but the species of that region are so entirely different from our own in facies and depend for their separation on characters not applicable in our fiuina, that his work has been of no assistance in the preparation of this. In this essay Mr. Watei-house has separated one of our species (pulchellus), which has an equivalent in Mexico, from Ar/rilas under the name Engyaulus, but for reasons which will be found under our species, the genus is not considered well founded. 278 GEO. H. HORN, M. I). The species described by Gory are barely recognizable, and the figures give but little aid. He seems not to have known of the species described by Say, or else purposely disregarded them. It being veiy evident that the unsatisfactory work ])reviously done with our species w'as due to insufficient material, and the neglect of an examination of the sexual characters, no attemi)t has been made by me to record my observations until reasonably full series had been obtained with the sexes of each species represented. In the following pages but one species is represented by a single specimen, and of about four others two of each have been examined. As a general rule, our species are .not marked by any great surface irregularities, such as deej) thoracic depressions and strongly elevated elytral costte. The only exceptions aie cavaius and Couesii, the former being represented in Mexico and the other may also be. At ti]) the elytra are simjdy acute or rounded, never divergent, and variously formed as in many of the INIexican species. The colors are never very brilliant, nor is the ornamentation by pubescent spots very striking. The monotonous aspect of our species has com])elled a search for structural characters wdth very encouraging results, for with such characters, the limits of species may be more accurately defined notwithstanding any variation which may occur. In order that the systematic portion of this work may be the better understood, the various portions of the body showing important modifications will be reviewed consecutively. Antenna. —The form of these organs seems to have been entirely neglected. In some species the antenme are slender and long (PI. viii, figs. ]1-13), in others short and comparatively stout (PI. viii, figs. 12-14), in the former case the joints are longer than wide, and in the latter as wide, or even wider than long. The most im])or- tant modification observed is in the mode of their serration. By far the larger number of our species have the antennce serrate be- ginning wdth the fourth joint (PI. viii, figs. 11, 12); in the others the serration begins at the fifth joint (PI. viii, figs. 13, 14). There may be at times a (juestion wdth those who study this character for the first time and in some species it might be difficult to determine to which series it should be referred, but whenever the fourth joint resembles the fifth more nearly than it does the third, the species belongs to the first series, but when the third and fourth joints are similarly cylindrical then the species belongs to the second series. NORTH AMERICAN COLEOPTERA. 279 Head. — The front may be flat, moderately convex, or very con- vex. In the latter case the month seems more retracted and inferior, as will be observed in the sjiecies from jmlchelhis to muticus, but va- rying in degree, so that this character fails to be useful foi’ generic separation. In nearly all the species the head has a median im- ])ressed line beginning at the occiput, but this varies both in extent and depth, forming in several sj)ecies a deep frontal depression or even concavity. The clypeus varies somewhat in form, but not to the extent observed in Chrysobothris, so that no use has been made of it in the table. Sexually the head varies in sculpture and coloi', as will be found recorded, but the differences between the sexes are not by any means as well marked as in Chrysobothris, or in the more closely allied Anthaxia. Other characters of more resti-icted oc- currence will be found under the species in which they occur. Prothorax. — The usual thoracic characters based on color, sculp- ture and the depressions require no S{)ecial comment. The carina of the hind angles has nearly always been mentioned from the earliest descriptions, and its presence or absence regarded as an infallible sign of specific distinction. It remains now to be recorded that in a number of species the presence or absence of the carina is often purely sexual, the male being without it. This is well shown in a series of acutipennis. In all cases the presence or absence of carina must not be assumed to be of specific value, except when accompanied by other characters. The lateral marginal edge of the thorax assumes two forms when viewed from the side, the sinuate and straight. The former is the more usual, and is well illustrated by macer (PI. viii, fig. 9), while the straight form is mostly seen in the cylindrical species, such as lacndris, etc. (PI. viii, fig. 10). Prosternum. — The prosternal lobe varies in length and form, sometimes almost entirely concealing the mouth. Its anterior margin may be broadly rounded as in cavatm (in which the mouth is nearly concealed), truncate as in bllineatus, or emarginate, as is the more usual occurrence. Various forms of emargination will be observed, the most irregular being in difficilis, in which the notch is small, and on each side there is a sinuation. The tip or apex of prosternum is subject to great modification. In many species the tip is continuous with the intercoxal portion and enters the metasternum by a triangular notch, while in others the tip is abruptly bent upwards and enters the metasternum concealed. 280 GEO. II. HORN, M. D. This structure has been well described by Mr. Waterhouse. When the tip of the prosternuni is closely applied to the metasternum, the portion of the ape.x not concealed assumes various forms, being tri- angular, rounded, truncate or dilated (see muticus and species near). For convenience of expression in the analytical table, the visible free portion has been assumed to be the tip, and is so spoken of in the table. SciTTEEEUM. — The two forms observed are charactei’ized by the presence or absence of a transverse carina. This structure seems to have been considered as invariable as the angular carina of tli,e thorax, but in several of our species the carina may be distinctly jiresent in some specimens and entirely absent in others. Elytra. — In nearly all of our species the sides of the elytra are slightly sinuate behind the humeri, and then more or less dilated before finally narrowing to the aj)ex (PI. viii, fig. 7), but in many others the elytra narrow from the luuneri to the apex almost without sinuation as in difficilis (PI. viii, fig. 8). In the former case the sides of the abdomen are much less visible from above than in the latter. As a rule the elytra are narrower in the male. The disc is not often costate and then only in the species of the tropical ty[ie, as in Couesii, cavatns and macer, but in very many species there is on each elytron a very vaguely indicated costa. The surface sculpture is practically the same in type in all our species, and is derived from a form described as imbricated, resem- bling, when magnified, a series of pointed tiles, closely placed, in which the points are somewhat elevated. The sculpture in s’ome species might be described as closely mucronate. The apices of the elytra are not, in any of our species, provided with the curious prolongations and modifications seen in the tropical forms. The tip is rarely very acute {nevadensis) , usually rounded. The edge is usually serrulate, and in a few species entirely sim[)le (jmdicus, etc.). PvGiDiUM. — In very nearly all our species the pygidium is pro- vided with a median smooth or elevated line, in many species forming (piite a ridge, and in a good number the ridge is ])rolonged, forming a spine sometimes emarginate at its apex {macer). The presence or absence of the prolongation is one of the most constant of the struc- tural characters, although specimens of rnficolUs are occasionally seen without it. The pvgidium oi pulchellm is acute at tip, the carina well marked, but not independently projecting. NORTH AMERICAN COLEOPTERA. 281 Abdomen. — The principal modifications of the abdomen are due to sexual pecnliarities of the male, which are sufficiently described under the species in which they occur. Several pecnliarities have been observed which are not sexual. In ventralis the middle of the posterior edge of the second segment is free and prolonged slightly over the next segment ; the same is observed in the third segment, but in a less degree. The sides of the last ventral segment are nsnally simple, but in a few species (obolinm, Wahinc/liami) the edge is dis- tinctly serrulate. The apex of the segment is rounded or oval, ex- cept in a few species (conciniins, acutipennis), in which it is truncate. In iiiine of our species is the last ventral emarginate, as in many European species. Along the side of the abdomen there will be observed a well ele- vated ridge, which is sometimes interrupted on the first or second segments, usually more or less sinuous in front. Although variable within certain limits it is not sufficiently so to warrant any use of it in the grouping of species. This line divides the ventral segments, so that the upper jiortion, usually sub-elytral, has been called, for conveidence, the “vertical ])ortion of the segments;” it is often dif- ferently clothed from the inferior part of the segment. The suture between the first two segments is usually entirely ob- literated, but in Walsinghami \s visilile at the sides; in some speci- mens of acutipennis, and more rarely bilineatus, the suture is faintly indicated. The pre.sence of this suture has affi)rded Mr. Waterhouse the means of separating a small number from the mass of species in Mexico. Legs. — The legs in all the species are slender, and afford very few characters useful in separation. In a good number sexual differences have been observed in the tibiae, consisting of a short spine or mncro at the inner apical angle of the anterior tibia and sometimes {otiosus, etc., FI. viii, fig. 18) on all the tibiae of the male; the female tibiae are simple in all the species. The tarsi vary, apparently, in length. Apparently, because in estimating their length some comparison must be made with adjacent parts, and it will be found in nearly every case the tarsi bear the same relation in length to the tibia. The claws vary greatly in form, affording nsefnl characters in grouping the species, although the demarcation is not so sharply defined as to render differences primarily useful. In no case are the claws simple, or even approaching that condition. Mr. Crotch remarked that while the claws of many European species TR.VN.S. AM. ENT. SOC. XVIII. (3(3) SEPTEMBER, 1891. 282 GEO. H. HORN, M. D. were bifid, they were not so in any American form that he had seen. It seems to me that a careful homological study of the claws shows that in all our species these members are either bifid, or of a modified l)ifid form. While they are usually called cleft, there is no truly cleft claw in any species. If we examine the species related to }W- litus and those near torpidus, the claws will he found so nearly of the true bifid type that they should he called so. Tracing the modifica- tions of this form it will be observed that the inner member of the bifid tip gradually shortens and broadens, while it preserves its lateral position in relation to the other part, although becoming quite a broad tooth. It seems not to have been noticed that in the group above indicated the claws are not only different in the two sexes, but, especially, in the male, different on the three pairs of feet. This effectually pre- vents anything but the most I’estricted use of the forms of the claws in separating either groups of species or species themselves. As the descriptions of the modifications of the claw would be an unnecessary rei)etition at this time, the student is referred to the remarks under each species. At this time I desire to acknowledge the assistance received, with- out which this essay would have fallen short of its present complete- ness. The Museum of Comparative Zoology has permitted the free use of the LeConte collection for conq)arison, without which the names here used would have less certain value. The National Mu- seum, through its Curator, Dr. C. V. Riley, has loaned its material, which has in one case removed a doubt from my mind, and in several others prevented the necessity of describing from uniques. The cabinet of the American Entomological Society has ako been freely used. To Messrs. Ulke, Liebeck, Seeber, Wenzel and Henshaw, I am indebted for the free use of their material and the gift of speci- mens. Finally, to Mr. Fred. Blanchard, of Low’ell, I am under especial obligations for his many useful suggestions, and for his hav- ing very kindly studied several difficult questions regai’ding the of imus senes on the carefully collected material in his cabinet. The meaning of the expressions used in the subsequent j>ages of the essay having been sufficiently explained, the following table is presented to enable the species to be, at least approximately, deter- mined. The arrangement of the species by the sequence in the table does not in all cases ajjproximate those having a superficial resem- blance. The object of this study is to enable the determination of NORTH AMERICAN (^OLEOPTKRA. 288 the species and the minor detail of a cabinet arrangement can he left to the judgment of those who possess a sufficient number to make it desirable.

This species was not identified by LeConte. The name Sayi Saund. was unnecessarily suggested for it. Buprestis granulata, vol. ii, p. 104. The description of this species was amended on p 596. Was at one time supposed to be quadriguttatus Gory. Buprestis geminata, vol. ii, pp. 105 and -595, is the female of otiostis. See remarks below. Agrilus ruflcollis, Fab. vol. ii, p. 595. From this time Say calls all the species Agrilus. Agrilus geminatus, vol. ii, p. .595; see above. Agrilus politus, vol. ii, p. 596 ; see above. Agrilus arcuatus, vol. ii, p. 596 ; see above.

Agrilus fallax, vol. ii, p. 596. Agrilus putillus, vol. ii, p. 597, was unknown to LeConte. Agrilus otiosus, vol. ii, p. 597. This is clearly the male of geminata, described about thirteen years previously, but as the more recent name has been adopted, and in general use everywhere, it has been retained for the species. As Say described both, and as one or the other must be a synonym, it seems to matter but little which one is suppressed. .4. (liflioilis Gory. — Form elongate, piceous, with a faint greenish or cupre- ous surface lustre. Antennae piceous, slightly bronzed, reaching beyond the middle of the thorax, serrate from the fourth joint; front flat, closely coarsely punctate, obsoletely bituberculate and with short pubescence, occiput slightly impressed. Thorax broader than long, slightly narrowed at base, sides slightly arcuate, the marginal line from the side slightly sinuous, disc convex, a feeble oblique lateral concavity, a faint ante-scutellar depression, surface rather finely transversely strigose, punctate at apex, hind angles with a rather strong arcuate cariuji ; scutellum transversely carinate ; elytra narrow, scarcely dilated behind the middle, apices rounded and serrulate, basal fovea rather feeble, disc convex, with faint costa, the surface punctate, but not close, becoming imbricate near the apex; body beneath with more decided metallic lustre ; prosternal lobe rounded, with an acute emargination at middle, the inter-coxal process broad, parallel and obtuse at tip ; prosternal pleurm punctate and pubescent, meso- and metasternum at sides more densely punctate and similarly j)ubescent, along the middle much smoother; ventral segments along the middle sparsely punctate, first segment at sides densely punctate, .strigose; the second, third and fourth segments with a more densely punctate spot conspicuously pube.scent, the vertical portions of all the segments pubescent in front ; pygidium coarsely sparsely punctate, with a median carina not jirojecting ; claws similar on all the feet. Length .36 — .52 inch. ; 9—13 mm. 288 GEO. H. HORN, M. D. Male. — Front flatter, more densely, but more finely pnncfate, nsually greenish in color; prosternnm densely punctate along the middle with (piite fine, sub-erect, silken pul)escence ; metasternum convex ; ventral segments similar in the sexes, not impressed. Female. — Front more coarsely punctate, color more or less cupre- ous; prosternum rather coarsely, not closely punctate, not pubescent. Variations. — The only variations noted are those of size and color, which do not change the aspect of the species in any great degree. Of the habits of this species nothing has been recorded. This is one of the larger species in our fauna, although several exceed it in size. The claws are cleft, and with the lower portion incurved, as re- (piired in the group, although less incurved than usual, so that the ])oints are (piite distant. This divergence from the tyjie of the group is the more marked in the male, the claws of the other sex being nearly contiguous. Hab. — Occurs in the Mississippi Valley from IMissouri to Texas. A. 11. sp. — Form robust, obscure seneous, opaque. Autenuae short, serrate from the fourth joint, slightly cupreous; head densely coarsely punctate, slightly strigose on the occiput, lougitudiiially impressed from the occiput to the clypeus.

Length .36 inch. ; 9 mm. Male. — Prosternnm densely punctate and rugulose sparsely, finely pubescent. Ventral segments not impressed. Female. — Unknown. The two specimens before me show no variation. The entire obliteration of the marginal line on the first two ventral segments is a character not observed elsewhere in our species. In form and general appearance this species resembles obolinns, which is also remarkable in having the marginal line of the abdomen faintly indicated on the first segment. llab. — Texas, ])robably near the lower Rio Grande.

Length .40 — .,50 inch. ; 10 — 12.5 mm. Male. — Prosternum densely punctate and pubescent along the middle ; metasternum convex ; first ventral segment slightly de- pre.ssed at middle posteriorly. Female. — Prosternum more sparsely punctate and not ])uhescent, first ventral segment convex at middle, le.ss closely punctate in the male. Variations:. — So few specimens have been collected that hut little variation has been observed. The thorax is entirely cupreous, the median line more golden, and on each side of this is a longitudinal space of darker color, which varies in its intensity of color and extent. Of its habits nothing is known. Hab. — Tennessee and Georgia. .V. riitirollis Fab. — Black, or blue-black; head and thorax usually bright cupreous.

Length .22 — .28 inch.; 5. .5— 7 mm. Male. — Front more deeply impressed, less coarsely jninctate ; elytra not wider at the post-median expansion tlian at the humeri ; proster- num more coarsely punctate, metasternum slightly concave ; first ventral segment concave along the middle, the second segment rather deeply grooved for three-fourths its length, the groove smooth. Female. — Front flatter, more closely punctate, less deejily grooved ; elytra wider at the })osterior dilatation than at the humeri ; proster- nuin more spansely punctate, metasternum convex ; first two ventral segments not grooved, the surface smoother than in the male. Variations. — The normal and most common form has the head and thorax of bright cupreous color, the elytra black, .sometimes with a slight tinge of blue. The color of the head and thorax is, at times, quite brassy shading gradually to green. Specimens more rarely occur with these j)arts quite black, although with more gloss than the elytra. In all other characters excepting size, the species is re- markably constant. Habits. — The larva of this insect feeds in the stems of Blackberry and Raspberry, emerging in the early Summer. An excellent article illustrating the injuries done, together with a figure of the larva, will be found in “ Insects Injurious to Fruits,” by Wm. Saunders (J. B. Lippincott Company). Hab. — Occurs from Canada and the New England States south- ward to Virginia and westward to Missouri. A. lateralis Say. — Form of ruficollis. Head and thorax cuiireous; elytra black, with slight feneous lustre.

Length .25 — .28 inch.; 6.25 — 7 mm. Male. — Pmsteriumi coarsely, not closely punctate, without jtubes- cence ; first ventral segment slightly depressed along the middle, second with a deep, smooth groove extending more than half its length. Feiaale. — Prosternum less punctate, smoother ; first two ventral segments simple. Four specimens have afforded the above description. Another specimen in Mr. Ulke’s collection is of somewhat larger size, and with more even thorax, seems to belong here, although the discovery of the male may prove it distinct. This species greatly resembles ruficolUs, but may be distinguished by the less deeply impressed head and the presence of either a slight evidence, or a distinct carina, in the hind angles of the thorax. The sexual characters of the two are practically identical ; several other species have also some resemblance, but these have no pygidial spine. HabiU — The wood in which the larva lives is not known, but the imago has been taken on foliage of Poplar sprouts (Blanch. Ent. Am. V, p. o2, under the name auxins). Hab. — Massachusetts (Blanchard), New Jersey (Liebeck), New Mexico (Ulke), Illinois (Dury), Missouri (Say). .4. otioKiis Say. — Form slender, sometimes linear in the male, stouter in the female, usually dull greenish, sometimes slightly cupreous. Antennae usually bluish, extending nearly to the hind angles of the thorax, a little shorter in the female, joints all longer than wide, serrate from the fourth joint; head viewed from above slightly convex, with a very slight occipital impression, front rather flat, coarsely and closely punctate, occiput faintly strigose. Thorax a little wider than long, slightly narrowed at base in the male, sides feebly arcuate, but more distinctly in the female, lateral edge straight , or feebly sinuous hind an- gles obtusely or indistinctly carinate , or usually with a well defined carina 9 , disc convex, an oblique lateral depression and on the median line two depres- sions, the posterior the larger; surface transversely strigose, with fine punctures between; scutellum transversely carinate; elytra slightly sinuate behind the middle, entii-ely concealing the abdomen from above, apices separately rounded, finely serrulate, elytra with a vague costa from the humeri behind the middle, between which the elytra are slightly flattened, and behind the middle the su- 292 GEO.

Length .16 — .22 inch.; 4 — 5.5 mm. J/a/e. — Form more slender, sometimes tilmost linear; front flatter, more densely punctured ; hind angles of thorax less distinctly cari- nate ; prosternum densely, finely punctate, finely pubescent, the pu- bescence usually extending along the median line of the body to the end of the second ventral segment ; first two ventral segments vaguely sulcate on the median line. Inner apical angle of all the tihiie spiniform and incurved. Female. — Form stouter, usually with more evident leneous surface lustre ; front slightly more convex, more coarsely, but less closely punctate, the occipital impression extending slightly downward ; hind angles of thorax (piite distinctly carinate ; prosternum much more sparsely |)unctate, not hairy ; first two ventral .segments not im- ]>ressed and with smoother scul])ture. Variations. — The most striking structural variation is the hind angles of the thorax. The sexual variation has already been re- corded, but s])ecimens are before me as completely deprived of carina as any species in our fauna, not only males but females also. The smaller and less developed males have the ventral sexual characters less pronounced, so that the pubescence along the median line be- comes less distinct and the sulcus of the first two ventral segments almost entirely disappears. The color variations are not great, the males, however, are in a great part dull bluish, while the females are slightly greenish or cupreous. As this is a common and well known species, much space has been given to its description as a means of comparison for other species. Say’s A. geminaius is undoubtedly the female (T this, suhsecpiently described by him as otiosus. The former name has priority by sev- eral years, but the latter name is retained from its having acquired general acceptance, and from the fact that both belong to the same author and no injustice is done. This is clearly one of those cases in which the law of priority should yield to that of convenience. Habits. — Feeding on Oak shrubs (Blanch. Ent. Am. v, p. 32).

Thorax wider than long, not) narrower at base, sides arcuate from apex to base, hind angles obsoletely carinate in both sexes, lateral margin very nearly straight, disc convex, a vague oblique depression at the sides, two dei)ressions on the median line, but feebler than in otiosus : surface trans- versely strigose, the grooves punctate, more distinctly than in otiosus ; scutellum transversely carinate ; elytra sinuate behind the humeri with the post-median dilatation concealing the abdomen, apices rounded, finely serrulate, disc with scarcely a trace of costa, the sutural border elevated behind the middle, basal depressions feeble ; surface imbricately sculptured, but smoother near apex ; body beneath more shining, dull bluish green ; prosternal lobe obtuse, vaguely emar- ginate, the intercoxal process gradually narrowed and acute at tip, propleura? moderately closely punctate; metasternum not closely imbricate. Abdomen sparsely punctate along the middle, a little more closely at the sides; pygidiuin coarsely sparsely punctate, feebly carinate; tarsi slender, as in otiosus; claws similar on all the feet. Length .16— .18 inch.; 4 — 4.5 mm. Male. — Front more opaque and finely punctate; prosternuni coarsely, not clo.sely punctate, rather opaque. First two ventral segments faintly grooved, but not pubescent ; last ventral truncate, with a marginal fringe of hairs, curved and directed downward. Inner apical angle of all the tibiae s])iniform, slightly incurved. Female. — Front more shining and more evidently punctate ; pros- ternum more shining. First two ventrals not grooved, last ventral oval at tip, not fimbriate. Of the habits of this species I have no information. The only variations observed are those of color as in otiosus, the females rather more brassy. There can be very little doubt that this species was originally in- stituted to contain all the small specimens of otio.ms in which the Carina of the hind angles of the thorax is nearly or (piite Avanting. An examination of the series showed, however, that, abstracting the true otiosus, there remained specimens, one of which bore the type label, which clearly indicated a distinct species. They were, how- ever, females. A few days later Mr. Blanchard gave me a male, which was clearly a mate for the type. As might be inferred from the preceding i-emarks, the sjiecies very closely resembles small or starved specimens of otiosus. There need be no ditficulty, whatever, in separating the males from any Agrilus in our fauna, but the fe- males are more difficult. It will be observed, however, that in the 294 GEO. H. HORN, M. D. present species the median line of the abdomen is very smooth, almost without punctures. In fact, the entire abdomen is less sculptured than usual. When once a male is obtained there will be no great difficulty in separating the female from otiosiis. It is evident that LeConte had before him a male of this species which he mistook for the male of laeu.st7'i.s, but I failed to find the specimen at present associated with that species, and discovered that it had been removed and placed with the present species either by himself, or later by Crotch.

Antennse slender, bluish, passing the hind angles of the thorax, joints all longer than wide, serrate from the fourth joint, fimbriate on the posterior side with comparatively long, sparsely placed hairs; front rather fiat, a slight occipital depression, subopaque, sparsely punctate, occiput faintly strigose. Thorax wider than long, slightly narrowed at base, sides arcuate, margin slightly sinuous, hind angles not at all or very feebly carinate, disc moderately convex, a deep oblique lateral and two mele; surface transversely strigose, with punctures between the strigse; in some specimens the striga? are very feehle; scutellum transversely carinate; elytra sinuate behind the humeri, slightly broadened behind the mid- dle, apices separately rounded, finely serrulate, disc slightly flattened at middle with an extremely vague costa; surface with imbricate sculpture, less close and more shining than in politus, with three indistinct pubescent spots, often merely indicated by a slightly denser punctuation, these spots placed as in nevadensis ; prosternum densely punctured, the lobe acutely emarginate at middle, the inter- coxal proce.ss i)arallel, acute at tip, propleurse densely punctured with consiiicuous whitish pubescence; metasternum at sides densely |ninctate and transversely sti’igose, pubescent as in the propleurpe. Abdomen sparsely punctate at middle, more densely at the sides and finely strigose, especially on the first two segments, vertical portions of the segments densely white jiubescent; pygidium coarsely punctured with a strong median carina, projecting at apex. Length .25 — .37 inch. ; 6.5 — 9.5 mm. Male. — Front slightly flatter; tibise not distinctly inncronate; claws cleft one-third from apex, forming an achte tooth ; first ventral segment flattened at middle, the second with a slightly depressed, smooth space at anterior half of middle. Female. — Front slightly convex ; tibite not inncronate; claws cleft at middle, forming an acute tooth. Ventral segments convex at middle, the first much smoother than on the male. VariatioiU. — The color variation has been referred to. In many specimens there is on each side of the median line, nearer the front, a fovea which is as often absent. In very carefully collected speci- mens the sides of the thorax above have a white efflorescence, and the body beneath, at sides, seems very densely pubescent, owing to the efflore.scence between the hairs. This is, however, so easily lost, one might readily suppose two specimens to be distinct species which had been unecpially handled in collecting. The three jnibescent spots on the elytra are, at best, very feeble, and some care must be used in their observation. Habits. — Nothing is known to me.

Thorax broader than long, not narrower at base, sides regularly arcuate, lateral margin sinuate, hind angles with a fine, short Carina; disc convex, but irregular, a vague depression in the front and base of the median line, sometimes a fovea on each side; lateral oblique impressions distinct, but short; surface vaguely transversely sirigose and punctate; elytra slightly sinuate behind the humeri, and a little broadened behind the middle apices subacute and serrulate, disc slightly flattened, the sutural edge elevated from the middle to the apex ; surface imbricate, more closely at a])ical third and in the basal foveae, which are modei'ately deep ; body beneath similar in color to the upper surface, but more shining; prosternal lobe feebly emarginate at mid- dle, the intercoxal process moderately broad, acute behind the coxae, the pro- pleurae grauulate-imbricate, sparsely pubescent; metasternum at sides roughly imbricate. Abdomen finely punctate, very sparsely at middle, more closely at the sides, the first segment finely strigose, the outer surface including the ver- tical portion of the segments finely and sparsely pubescent; last ventral segment very obtuse or truncate ; pygidium coarsely punctate, with a strong carina, w'hich projects at tip ; claws dissimilar.

Female. — Front cupreous, and somewhat more convex. Proster- num but little smoother than the male. Ventral segments simple; tibise not mucronate; claws broadly toothed on all the feet. The six specimens before me show no variation. In its general appearance the species greatly resembles some of the forms of politus. From the species which seem most closely related to this (anxms and Blanchardi) the present differs primarily in color, this being cupreous, they olivaceous. Color characters are, however, not greatly to be regarded, as great variations do occur. On the male sexual characters it is better to place more reliance, as these are far more constant.

Abdomen finely ])unctate, s]>arse along the middle, closer along the sides and dense at the side of the first segment; vertical portions of the segments finely pubescent, apical segment truncate; pygidium coarsely punctured and with a median carina pro- jecting strongly at apex ; claws dissimilar on the feet.

Female. — This sex has not, with certainty, been found among my specimens. It probably differs from the male in the manner usual in the group. In well preserved specimens of this species the underside of the body is more or less clothed along the side with a whitish efflores- cence, whereby the pubescence is made more evident, and apparently more dense. This species closely resembles pensus and auxins, so that it will be difficult to separate the females, especially from the latter, but the ventral characters of the male will enable it to be at once recognized.

Female. — Head somewhat' cupreous, less densely punctate. Ven- tral segments simple; tibiie not mucronate; claws broadly toothed at basal half. ■ The color of this species is remarkably constant, varying but little from olivaceous, becoming but slightly green or plumbeous, resem- bling closely both pensus and Blanchardi, from either of which ref- erence must be had to the male characters for separation, although the carina of the hind angles of the thorax is, in both sexes, stronger and more arcuate than in any species related here. In my cabinet a male specimen from an unknown locality agrees in all particulars, except that the hind claws have the same form as on the middle and front feet, and the angular carina is much less distinct. While it may represent a different species, it seems preferable to allow it to pass with mere mention.

Ventral segments convex at middle, not grooved. Variaiiona. — Two well marked varieties may be indicated based on color, between which there are, however, distinct intermediates. Var. acutipennis Mann. — Color deep blue, becoming blue-black in one direction, or slightly olivaceous in the other. This form is usual in the more southern regions, although my darkest specimen is from Massachusetts, as well as that intermediate between the blue form and the next variety. Var. . — Color olivaceous, the thorax somewhat brassy. This variety seems confined to the more northern regions of the country ; in fact, all I have seen are from Massachusetts. Habits. — j\Ir. Blanchard states that he has taken the acutipennis form on the foliage of Oak shrubs, the other on foliage of Poplar si)routs. These observations do not give any positive indication of the wood into which they bore.

Head broadly concave, more deeply impressed along the middle, a tubercle each side of middle of front, a rather deep transverse groove above the base of clypeus, between the antennal fovea, surface very coarsely punctate, occiput slightly strigose. Thorax one-third wider than long, slightly narrowed at base, sides feebly arcuate, mar- gin sinuous, hind angles rectangular, with a slight obtuse elevation in the male and a feeble carina in the female; disc moderately convex, with a broad and rather deep groove extending from base to apex, sides obliquely depressed, sur- face punctate and rather coarsely strigose, except on a space each side of median groove, broadly clothed with yellowish white pubescence at sides: scutellum not transversely carinate: elytra slightly sinuate behind the humeri, feebly broad- ened behind the middle, apices obtusely rounded, serrulate, disc comewhat flat- tened. with a very well defined costa extending from the humeri very nearly to apex, in latter region slightly sinuous ; surface pubescent, but forming a distinct vitta within each costa, extending from the feeble basal depression to apex and near the latter region twice interrupted, punctuation dense and fine between the cost*, coarser exterior to them ; body beneath more shining than above; proster- uum sparsely punctate in both sexes, the lobe emarginate, iutercoxal process broad, obtusely pointed at apex, propleui-* densely punctate, somewhat strigose. distinctly pubescent; metasternum at middle sparsely punctate, at sides more densely and finely and with the episterna and outer half of coxal plate pubes- cent. Abdomen very sparsely punctate at middle, first and second segments with a densely punctured and pubescent stripe at a distance from the lateral margin, the next three segments with a pubescent triangular spot at sides, the lateral marginal line on the first two segments indistinct and sinuous, the vertical por- tions of the segments densely pubescent; pygidium with a feeble carina, which does not project ; claws cleft, forming a broad tooth in both sexes. Length .38 — .44 inch. ; 10- 11 mm. Sexual characters. — The sexes are differentiated with some difficulty. I observe that the male has the dorsum less depressed and the carina of the hind angles merely a feeble elevation. Very few specimens have been seen, and no variations observed. This species and cavatus are of an entirely different facies from the remainder of our species, being of the type more commonly observed in Mexico. It has been supjiosed to be identical with perkicklns Gory, an opinion which Crotch thought not well founded. Occurs in Arizona and southern New Mexico (Snow). 310 GEO. H. HORN, M. D.

Length .36 — .,56 inch. ; 9 — 14.5 mm. Sexual characters. — The males may be known by their smaller size, more slender form, the abdomen less dilated beyond the sides of the elytra, the elytral costa better defined, and the tuberosity in the hind angles of the thorax less so. There are no ventral characters. The claws are cleft quite near the tip, forming an acute tooth in the front and middle claws, more broadly toothed on the posterior. The tibite are not mucronate. The female claws do not differ. Variations. — When carefully collected specimens are at hand the elytral vitta extends from the humerus two-thirds to apex, forming at its end a denser spot, on each side there is a short pubescent vitta opposite the end of the former and a short distance in the front of the apex a small pubescent spot. By abrasion the greater ]>art of the vitta is often lost, and there then remains a basal spot, the denser end of the vitta and the ante-apical spot.

Length .50 inch.; 12.5 mm. In the five specimens examined no sexual differences have been observed. Tlie posterior tibite have a form wliich has not been observed in any other of our species. Near the apex the tibia is rather abruptly narrowed. The fringe of short bristly hairs which is observed along the posterior edge of the tibise in all the species in a varying degree is here present, but ends abruptly at the point at which the tibia is narrowed. The facies of this sjiecies is so unlike the style of those of our fauna, that 1 remained for some time in doubt as to the correctness of the locality. Recently, however, a specimen has been sent me from the National Museum removing all doubts. Hub. — Georgia, Florida (Nat. Mus.). .4.

Sexual characters. — Although both sexes are before me, tliere seem to he no external characters by means of which they can be se})a- rated, excepting that all the tibite of the male have a short mucro at tip on tlie inner apical side, while in the female tliey are simple. Variations. — Beyond the color nothing has been observed. The pubescent spots may be abraded, although they seem unusually per- sistent. The smaller spots, jiosterior to the base, form on the elytra an elongate hexagon. Hab. — Oregon and northern California ; Boise City, Idaho ; Luna, N.

Female. — Head dull cupreous or purplish ; prosternum sparsely indistinctly punctate, scarcely jiubescent ; claws acutely toothed a little in front of middle. In the two females before me the underside is purplish black, in- cluding the legs, while all the males are brassy. Variations. — In the males the thorax is green, inclining somewhat to purplish occasionally, while the two females are deep purple. The sides of the elytra in both sexes are cupreous, sometimes seneous in the males, the intermediate space green, varying to purple in the male, and ])urple in the female. For this species and one closely allied from Mexico, Mr. Water- house (Biol. Cent. Am. vol. iii, ])t. 1, p. 50) has suggested the generic name Eng^jaulus, which he separates from Agrilm by the convex front, and the mouth consequently more inferior, and the short first joint of the posterior tarsi. In a study of our species these charac- ters are shown to have no value, as will be seen by an examination of the form of the head in the species near which pidchellus is placed — Walsinghami, obolinus and mntieus. While the first joint of the hind tarsus is short, it is still equal in length to the next two, so that when conqiared with these or with the tibia the length is scarcely less than in very many species before me. From the fact that there are no valid characters for retaining Engyavlus apart from Agriius our species is returned to the latter genus. Hab. — Arizona and Colorado.

Variations. — In recent specimens the surface is clothed with a very tine, short pubescence, which gives them a pruinose aspect, the vast majority of cabinet specimens have no {luhescence. The differences of color have given rise to several names which do not seem to he worthy of retention, even as varietal names inasmuch as the intergrading of color is so gradual as to render it impossible to separate them. A. cupreolm Lee. was founded on a uni(|ue of rather larger size than usual, jeneo-cupreous in color. .4. poliius Say, is the more common form of cupreous color.

The sculp- ture is less dense. These may be either bright brassy, blue or green. Habits. — This species lives on Willows in whatever part of the country it is found. Hab. — Canada and the New England States westward to the Pa- eifle coast, Kansas, Colorado, New Mexico, Arizona, Nevada and throughout California.

Variations. — Slight variations in color will be seen as usual in the dark species. The median impression of the thorax may consist of an anterior fovea or a feebly impressed median line. When the pubescent spots are removed by abrasion, this species, especially the smaller specimens, greatly resembles egenus, and great care must be used in separating them, but the serration of the an- tennae is quite different in the two species.

Variations. — No variation of moment has been observed. Badly preserved s|)ecimens are often without spots, but the elongate narrow form of the insect will make it easily known.’ This species is especially notable in the long slender legs. The hind tarsi are especially elongate, being longer than the tibia, the first joint longer than half the tibia. Habits. — Found on the foliage of Oak shrubs. Hah. — Massachusetts westward to Illinois, south to N. Carolina. A. scitiiliiM u. sp. — Form oi fallax ; head aud thorax brassy, elytra dark olivaceous, with pubescent spots as in ohsoleto-gnttatus.

Female. — Unknown. This species is not especially conspicuous among those with ornate elytra. With the form of fallax or egenus, the markings, when per- fect, resemble those of obsoleto-guttatiis, and from any of them the structural characters either of the antennae, legs or prosternum will .separate.

Sexual characters. — The only points noticed in the nninerons speci- mens examined are found in the more opafpieand sctmewliat nigulo.se prosternum of the male, while it is sjiarsely punctate and smoother in the female. No variations have been olxserved, the markings .seeming very constant. In some specimens there will be observed a golden hue about the margins of the pubescent spaces. Hab. — Southwestern Texas, no precise locality known. \, n. sp. — Form oblong, subcylindrical, cupreo-ffineous, moder- ately shining, elytra with faint siibsutural pubescent vitta.

Female. — Prosternum sparsely jtunctate ; ventral segments simple. Variations. — None have been observed in the many specimens seen . This species, like ventralis of the preceding series, resembles Taphroceras a.griloides, and in the present rather more so than in that from the fact that there is here no pubescent elytral vitta. When the thorax is viewed fi'om above and from behind, the scul|)ture has a reticulate appearance, but when seen from in front is very obliquely and not closely strigo.se. Hab. — Southern Arizona.

Female. — Front less impressed ; in this sex the transverse depression is more often seen. Prosternum rather sparsely punctate, not hairy. INIetasternum flat, not closely punctate, nor hairy ; ventral segments simple; tibiae mucronate. Variations. — The color is but little variable, but the pubescence may be more or less abraded. The median dorsal depression of the thorax may be more or less dee[), but still preserving the form of two foveae united by a groove. Nothing is known of the habits of this species, although rather widely distributed. Hab. — Canada to Texas.

Length .18 inch. ; 4.5 mm. GEO. II. IIORX, M. D. 82() 'File three specimens of tliis species examined were all females, .so that I am unable to state the sexual differences. They show no variation. This species resembles Lecontel (subfasciatus) so closely, that I found it mixed with that s[)ecies in my own and another cabinet. The form of the prosternal lobe will, however, separate them at once. Suiierficially, the sculpture of the middle of the thorax will distin- guish them. In this species there is a straight depression, Avhile in Lecontel there are two depressions, anterior and posterior united by a narrower depressed space. Hab. — Texas, no special region known.

Length .12 — .18 inch.; 3 — 4.5 mm. Male. — Head very densely punctate, cupreous. Prosternum sparsely pubescent; first two ventral segments impressed at middle, more deejily on the first. Female. — Front less punctate, teneous. Prosternum scarcely pu- bescent ; ventral segments simple. The numerous specimens examined are constant in appearance, varying only in size. There are but few species so obliquely strigose ou the thorax as this one, the strigosity beginning at the middle and running diago- nally forward, Tho.se so sculptured are I'eadily known by their structural characters.

Abdomen moderately closely finely punctate, denser at sides of first segment; pygidium sparsely punctate, not carinate ; claws dissimilar in the sexes. Length .22 — .24 inch. ; 5.5 — 6 mm. Male. — Front flatter, tlie median imprecision feeble. Thorax as long as wide, tlie sides nearly straight. Prosternuin roughly punc- tate, sparsely pubescent. Abdomen simple, the first segment rather rough at middle ; claws on all the feet cleft very near the apex, almost bifid ; tibite simple. Female. — Head more convex, the median impression deeper. Tho- rax a little wider than long, the sides moderately arcuate. Proster- num less rugose, scarcely pubescent. Abdomen le.ss rugose ; claws broadly toothed. Variation. — In this species, as in others already noted, there is be- tween the pubescence a whitish efflorescence, which makes the pu- bescence seem denser and whiter, but when this is removed by acci- dental moistening the reverse is produced. This species resembles jacobinm, of the preceding series, in form and color, but differs in the form of the antennm and the presence of the pubescent vitta. It resembles still mure blandus but that has no trace, whatever, of carina in the hind angles, and the proster- nal lobe is more distinctly emarginate. Hab. — Arizona, probably near Tucson. A. iiii|>exii!it u. sp. — Subcylindrical, slightly flattened above, dull cupreo- seneous, each elytron with three indistinct pubescent spots.

Prosternum densely punctured, sparsely pubescent, the pubescence extending on the metasternum, which is flattened and closely punc- tate ; first two ventral segments vaguely sulcate their entire length and pubescent in the depression ; tibiie simple. Female. — Head less closely punctate, the concavity a little more jironounced ; median depression of thorax well marked with a fine impressed line at bottom. Prosternum less densely punctate, scarcely pubescent. Metasternum slightly convex ; ventral segments not impressed. Variations. — In the two specimens before me the variations have been alluded to, and seem to be sexual. 'fhe pubescent spots of the elytra are not distinct in either speci- men, except at base of elytra, but are very plainly indicated by the denser and finer punctuation. Closely resembles Jinridanus, but in the latter the ])ygidium is not carinate, and there is scarcely a trace of median impression of the thorax. Hub. — Arkansas and Nebraska. \.

Abdomen moderately closely punc- tate, strigose at sides of first two segments; pygidium sparsely punctate, with a smooth median line; claws cleft, forming a broad tooth. Length .28 inch. ; 7 mm. Male. — Prosternum densely punctured, pubescent; first two ven- tral segments very feebly impressed along the middle, scarcely pu- bescent ; tibite not mucronate. Female. — Prosternum less roughly punctate, not pubescent ; ven- tral segments not impressed. The two specimens before me do not vary. The types are before me and show that while the species is fairly, but too briefly described by Crotch, its position in his analytical table is erroneous. He men- tions pubescent patches at the sides of the last three ventral segments, but this is merely the result of a slightly denser punctuation. Hah. — Northern Florida, probably near Jacksonville. A. addeiidiis Crotch. — Moderately robust, dull cupreo-aeneous, subopaque, elytra with three pubescent spots on each side, sometimes absent or very faint. Antennae piceous, serrate from the fifth joint, reaching the middle of the thorax ; head, from above, concave, a moderately deej) impression from the occiput to the clypeus, surface rather roughly granulate-strigose, sparsely pubescent. Thorax very little wider than long, slightly narrowed posteriorly, sides feebly arcuate, slightly sinuate in front of hind angles, which are rectangular and with a straight, well defined carina; disc convex, with at most a feeble median impres- sion, which may he entirely absent, lateral oblique impression moderate, surface closely transversely strigose; scutellum transversely carinate; elytra feebly sinuate at sides and but little broadened, apices rounded, feebly serrulate ; disc slightly flattened, a vague channel each side of suture, basal fovese feeble, surface moderately closely, but not roughly imbricate, the pubescent spots, when present, as in fall ax ; body beneath more shining than above; prosternal lobe obtusely rounded, with a vague sinuatiou at middle, intercoxal process parallel, squarely truncate at apex, propleurfe shining, indistinctly reticulate; metasternum at sides roughly punctate-strigose and with the episternum and outer side of coxal plate pubescent.

XVIII. •(42) OCTOBER, 1891. 330 GEO. H. HORN, M. 1). Yarlatiom. — Two forms may l)e separated in this species, those witli tlie i)ubescent spots well marked and those without them. The former variety shows some pubescence at the sides of the thorax and at the sides of the last three ventral segments. Those without spots show in nearly all the specimens the spaces with denser fine punc- tuation, but even this may be absent. In the typical specimens, as Crotch states, there is a tendency to form a basal and subapical spots. Between the specimens with no spots and the others I have every necessary link in my cabinet. The median thoracic imjn'ession is, at best, faint, but in some speci- mens entirely wanting, in others represented by a slight antescutellar depression. Hah. — d'exas (Belfrage), Arizona. .4, laciistris Lee. — Moderately elongate, nearly parallel, slightly depressed above, color variable, dark bronze, green or bine. Antennfe piceous. not reaching the middle of the thorax, serrate from the fifth joint: head convex, a feeble median furrow from the occiput to the middle of the front, surface roughly puuctate-strigose. Thorax scarcely wider than long, the sides feebly arcuate, slightly sinuate near the hind angles, these rectangular with a short fine carina, margin straight, deflexed in front only; disc convex, sometimes with a vague median impression, the lateral depressions absent, surface transversely and rather closely strigose, with fine punctures; scutellum variable, either carinate or not; elytra feebly sinuate at sides and but little dilated behind the middle, apices rounded, serrulate; disc slightly flattened, basal fovea feeble, surface closely and rather roughly imbricate; body beneath more or less blue; proster- nal lobe broadly rounded, intercoxal process rather broad, truncate at apex, pro- pleurse strigo.se and punctate, sparsely pube.scent ; metasternum at sides trans- versely strigose, not roughly nor closely. Abdomen transversely strigose, not roughly nor closely; pygidium sparsely punctate, not carinate; claws broadly toothed. Length .16 — .30 inch.; 4— 7.5 mm. Male. — Front scmiewhat more opaque. Prosternum densely punc- tured and hairy. Metasternum concave ami hairy; first two ventral segments rather deejtly impressed their whole length, the impression hairy; tibite simple. Female. — Prosternum coarsely sculptured, transversely strigose, but not hairy. Metasternum slightly convex, transversely roughly strigose, not hairy ; ventral segments not imjiressed. Vaviatmu. — The color varieties have already been recorded. The blue forms are, however, very rare. The scutellum may be trans- versely carinate or not, sometimes the carina is interi-upted in the middle. Fully developed specimens usually have the carina very distinct; in the small and feeble forms it is wanting. The same is true of the feeble median depression of the thorax. NORTH AMKKICAN COLEOPTERA. 331 This species was originally named from some small and feeble forms from the North, which, at first sight, are very unlike the larger forms from the Texan region. It is also evident that LeConte had speci- mens of another species along with his types as tlie so-called male is really that of defedus. At present the specimen is not found with tlie types, having |)robably been removed either by himself or Crotch. The larger Texan forms were described l)y LeConte as cuneus from a single specimen in Ulke’s cabinet. From not finding a type in the LeConte cabinet. Crotch subsequently named the specimens in my cabinet pubiventris.

Female. — Front slightly more convex, the punctures coarser and less clo.se, more shining, teneous. Prosternum not hairy ; ventral segments not impressed. Farndm/i,s.— Notwithstanding the wide area over which this spe- cies is distributed, there seems to be no variation, except slightly in color and size. Some of the narrower forms with a slight greenish color resemble offo.sqt.s considerably, but the structure of both antenuDe and claws will separate them. On the other hand, some of the forms oi fallax deprived of pubescence are apt to be mixed with the present species, and are not easy to separate without great care, but the form of the antenme and the flat base of clypeus in the present sj)ecies will render them separable. 332 GEO.

Pro- sterjuun and metasternum transversely strigose, not {)ubescent ; first two ventral segments convex, not closely ])unctate and not hairy. The numerous specimens examined show no variation, except a little in size in specimens from the most remote localities. The species resembles egenus somewhat, but is more robust, has shorter antenme and an entire prosternal lobe. Specimens of lacus- tris have been seen which somewhat resemble this one, but the male characters will then readily separate them.

Au- teunse reaching the middle of the thorax, piceous, serrate from the fifth joint, serrate joints wider than long; head convex, a feeble median impression from the occiput to the base of the clypeus, surface moderately closely coarsely punc- tate. Thorax wider than long, slightly narrowed at base, sides arcuate in front, slightly sinuate near the hind angles, which are rectangular and distinctly cari- nate. margin nearly straight, deflexed in front, disc convex, a broad transverse depression in front of base, so that, when viewed laterally, the median line of the thorax is more convex in the anterior half, lateral oblique depression mod- erately deep, surface moderately coarsely transversely strigose, with coarse punc- tures in the grooves; scutellum carinate or not; elytra sinuate at the sides, distinctly dilated behind the middle, apices rounded, serrulate ; disc flattened, usually a vague costa on each side, a feeble concavity each side of the suture, basal depressions feeble, surface with imbricate sculpture, not rough nor close; body beneath piceou.s, shining, faintly bronzed; prosternal lobe truncate and broadly emargiuate, the intercoxal process acutely oval at tip, propleurse punc- tate and strigose; metasternum at sides strigose and subreticulate. Abdomen sparsely finely punctate, a little more coarsely at the side of the first segment; pygidium sparsely punctate, not carinate ; claws broadly toothed. Length .12 — .16 inch. ; 3 4 mm. Male. — Front flatter and more opaque; flrst ventral slightly flat- tened at middle and rugose. F emale. — Front more shining and rather more convex ; first ventral convex and not roughened. Variations. — The general aspect of this species is that of a diminu- tive rujicollis with the thorax less conspicuously cupreous. The tho- rax is often brassy with purplish spaces at the sides. Sometimes the elytra are seneous. These last forms resemble jjutillus, but these have no carina in the hind angles of the thorax, and the disc has a distinct median impression. 334 GEO. H. HORN, M. D. This species was placed by LeConte in the group with the incurved tootli of the claws, but the claws and an ten life are both different from that series. The name parvus has been suggested for this species by Saunders in “ Catalogus Bnprestidarum,” but there seems to be no valid reason for the the change. It is certainly ])ermissible to use jnisUhis and putillus in the same genus. Hab. — Kansas, Colorado and Arizona. Bibliography and Synonymy- AGRILUS Steph. A. dififlcilis Gory, Mon.

The study of the Tachinidse has progressed considerably of late in the line of descriptive work. Up to within a few years a large number of forms, necessitating the foundation of new genera, had remained unnoticed. iNIr. van der Wulp has given us descriptions of a considerable number of these, which, however, are mainly con- fined to Old Mexico. Messrs. Brauer and von Bergenstamm have erected a great number of genera from all parts of the w’orld, some of which can be em})loyed ; but many are unfortunately either based on invalid characters, or insufficiently de.scribed and without figures to enable their recognition. A few other authors have contributed isolated descriptions of genera in this grou]). Notwithstanding these recent additions I believe it necessary at this time to erect a number of new genera for the reception of forms herein described, which cannot be reconciled with any of the published descrii»tions or figures of previous genera. The present jiaper is the result of a study of a considerable col- lection of material, all from within the limits of the United States ; and will, the writer hopes, contribute toward a more accurate know- ledge of our many species among these useful parasitic Hies. SIPHOPLAGIAf 11. gen. Belongs in the sub-group with Plagia, from which it differs prin- cipally by the elongate, slender proboscis, and absence of bristles on the sides of face.

Type, S', anomala n. sp. This genus diflers from Plagia, as above stated, by the structure of the proboscis, and the absence of rows of bristles on the sides of the face ; also by the macrochsetie being only marginal. It agrees with it in all other essential characteristics.

Genus Tachinodes Br. and Bgst., Zweifl. kais. Mus. W. iv, 133. This genus, so far as I can ascertain from comparison, of the descrip- tions, is the same as N^einochoeta v. d. Wulp. Mr. van der Wulp’s genus has priority, as it was described in 1888 (Biol. C.-A. Di})t. ii, 38). The above authors give no figure of their genus Tachinodes, which was erected for Tachina hystrix Fab. from Brazil. Tacliiiia spiiiosiila n. sp. 9 (’)• — Blackish cinereous.

Length 6 mm. ; of wing 4.5 mm. Described from one specimen received from Mr. Chas. Robertson, Carlinville, 111. This is a good, typical Taehina in the sense of Schiner; the only difference being in the nearly closed aj)ical cell. Doubtless, further specimens will show the apical cell to be normally more open. Taehina aletise Riley, Can. Ent. xi, 162. As the eyes are described “ thinly pubescent,” this is not a Trichina. Besides, the third antennal joint is said to be “three or four times the length of the second,” while in Taehina it is at most twice the length of the elongate second. The description is insufficient to indicate the genus. The surmise would be that the sjiecies belongs in Exorista. Taehina (Masicera) armigera Coquillett, Ins. Life i, 3.32.

The only differences between the above described Miltogrammas and Schiller’s generic description are that the arista is quite distinctly 3-jointed, and the third antennal joint is about twice the length of the second. ,^Iiltoj;raiiima argentif roiis a. sp.

Front silvery, iucludiug vitta, sides darker iu some lights; only three orbital bristles; frontal bristles not so nu- merous or closely set, rather sparse; anteunse entirely dull blackish, except apical rim of second joint, which is light yellowish, third joint scarcely longer than the second ; arista black, thickened only at base, bulbous, indistinctly jointed; sides of face finely hairy ; facial depression narrow, scarcely any bris- tles on facial ridges above the vibrissse ; palpi blackish or dark brown ; apical scutellar pair of macrochsetse sometimes not, but usually decussate. Abdomen blackish or dark brown, light cinereous pollinose, no distinct median vitta ; first segment with a weak lateral macrochgeta on the margin ; second with a lateral marginal one and a median marginal pair; third segment with eight marginal, and anal segment with six marginal, as in the above species. Claws and pulvilli elongate. Tr«(f/s smaller ; halteres flavous. Length 4 — 5.5 mm.; of wing 3.5 — 4.5 mm. Described from four % specimens received from Mr. Charles Robertson, Carlinville, 111. One of these specimens is much larger (5.5 mm.) than the three others (4-4.5 mm.), and also differs in hav- ing a median macrochteta (its mate probably lost) on margin of first abdominal segment. The sides of the face are only very slightly hairy. It does not otherwise differ appreciably. Mlltogramma trilineata v. d. Wulp, Biol. C.-A. Dipt, ii, 89. One specimen from S.

This species I have located temporarily in Masicera, although it does not (piite agree with the characters of that genus. The ajiical cell is opened only a little before the wing’s tip, and the form is rather narrower than is usual in Masicera. It apparently approaches Telothyria v. d. Wulp, but differs from it by the promi- nent front, receding face and distinctly 2-jointed arista. Additional specimens will be needed to decide its location. IIYI»KRTROPIIO<’ERA* n. gen.

(?) have })referred to locate this species in the genus Apliria, although in some features it closely approaches OUvierla, but differs from it also in others very essentially. The jiroboscis is long, but bardly bristle-like and not horizontally protruded. It is straight and per- pendicularly extended, of about the same size and length as in Ocyptera, but, unlike that genus, possesses well-formed palpi. The eyes are extremely thinly pubescent and the apical cell closed in the margin, both of which characters lead to Aphria in Schiner’s table, but are denied it in his generic characterization. From Olivi.eria it differs in the receding (not almost perpendicular) face, in the longer and more slender proboscis, and in the absence of discal macrochpetic on the abdominal segments. Nemonea 7nasnrius Wlk., N. clasides Wlk., and N. trixoicles Wlk. Mr. van der \Yulp has called attention to the fact (Biol. C.-A. Dipt, ii, 47) that none of these three species belong in the genus Nemnnv.a, since the eyes in all of them are bare.

This new genus and species is described from California, and was Itred from adults of Diabrotica soror. It is described as having five abdominal segments, wdiich would properly exclude it from the Tach- inidte sens, str., and it would fall in the Phaniidte by its other char- acters. The first or basal segment is, however, as long as the second, and the so-called fifth segment is probably not a segment properly speaking, but merely the more or less concealed caudal joint or hy- poiyygium to be found in many Tachinidte s. sti‘. In the OcyjJeridm and Phaniidm, as \vell as in the Phasiidte, the first segment is much shorter than the second, and it is at the ba.'ie of the abdomen that the additional segment must be looked for.

Described from thirty-three specimens taken on windows of Agri- cultural College building, June ‘29th to July 8th, Las Cruces, N. Mex. Some specimens differ in the frontal vitta being of equal width, wider than base of antennte in front, occupying throughout one-half or more of the frontal width. The probo.scis is often not so much bowed, sometimes nearly straight. The tar.si of some are shorter, particularly the distal joints, the claws and pulvilli being apparently a little less elongate. Yet these differences by no means constantly acconi[)any each other ; I am, therefore, uncertain of the NORTH AMERICAN DIPTERA. 371) sexes. The smallest individuals have the front and face only one- third the width of the head, and, were it not for their short claws and pulvilli, I should consider them to be the males.

Although the frontal bristles do not descend on the face and the arista is short feathered, this species seems to claim close I’elationship with Atrophopoda. The front claws and pulvilii in both are minute, and the general facies is strikingly the same.

In order to avoid confusion in the use of the word, I ])ropose for Meigen’s genus the name Neouromyia. Note on the Dexiid genus Tropidoniyia Br. and Bgst. — Brauer and V. Bergenstamm (Zweifl. kais. INIus. W. iv, 119, 1889), have erected a genus which they called Trop>idomyia, for a Dexiid from Syria. The name is preoccupied; Dr. Williston applied it to a South American Conopid, which he described in “Can. Ent.,” Jan- uary, 1888. Brauer’s genus must, therefore, be given another name, and I propose that of Neotropidomyia. ERRATA.
